Introduction
Cisco IOS XR software is a distributed operating system designed for continuous system operation combined with service flexibility and high performance.
Cisco IOS XR software provides the following features and benefits:
•
IP and Routing—Supports a wide range of IPv4 and IPv6 services and routing protocols; such as Border Gateway Protocol (BGP), Routing Information Protocol (RIPv2), Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), IP Multicast, Routing Policy Language (RPL), Hot Standby Router Protocol (HSRP), and Virtual Router Redundancy Protocol features (VRRP).
•
BGP Prefix Independent Convergence—Provides the ability to converge BGP routes within sub seconds instead of multiple seconds. The Forwarding Information Base (FIB) is updated, independent of a prefix, to converge multiple 100K BGP routes with the occurrence of a single failure. This convergence is applicable to both core and edge failures and with or with out MPLS. This fast convergence innovation is unique to Cisco IOS XR software.
•
Multiprotocol Label Switching (MPLS)—Supports MPLS protocols, including Traffic Engineering (TE), Resource Reservation Protocol (RSVP), Label Distribution Protocol (LDP), Virtual Private LAN Service (VPLS), and Layer 3 Virtual Private Network (L3VPN). The Cisco CRS-1 router supports Layer 2 Virtual Private Network (L2VPN).
•
Multicast—Provides comprehensive IP Multicast software including Source Specific Multicast (SSM) and Protocol Independent Multicast (PIM) in Sparse Mode only. The Cisco CRS-1 router supports Bidirectional Protocol Independent Multicast (BIDIR-PIM).
•
Quality of Service (QoS)—Supports QoS mechanisms including policing, marking, queuing, random and hard traffic dropping, and shaping. Additionally, Cisco IOS XR software also supports modular QoS command-line interface (MQC). MQC simplifies the configuration of various QoS features on various Cisco platforms.
•
Manageability—Provides industry-standard management interfaces including modular command-line interface (CLI), Simple Network Management Protocol (SNMP), and native Extensible Markup Language (XML) interfaces. Includes a comprehensive set of Syslog messaging.
•
Security—Provides comprehensive network security features including access control lists (ACLs); routing authentications; Authentication, Authorization, and Accounting (AAA)/Terminal Access Controller Access Control System (TACACS+); Secure Shell (SSH); Management Plane Protection (MPP) for control plan security; and Simple Network Management Protocol version3 (SNMPv3). Control plane protections integrated into line card Application-Specific Integrated Circuits (ASICs) include Generalized TTL Security Mechanism (GTSM), RFC 3682, and Dynamic Control Plane Protection (DCPP).
•
Craft Works Interface (CWI)—CWI is a client-side application used to configure and manage Cisco routers. Management and configuration features include fault, configuration, security, and inventory, with an emphasis on speed and efficiency. The CWI provides a context-sensitive graphical representation of the objects in a Cisco router, simplifying the process of configuring and managing the router. The CWI allows you to log in to multiple routers and perform management tasks.
•
Availability—Supports rich availability features such as fault containment; fault tolerance; fast switchover; link aggregation; nonstop routing for ISIS, LDP, BGP, and OSPF; and nonstop forwarding (NSF).
•
Multicast service delivery in SP NGN—MVPNv4 support carries multicast traffic over an ISP MPLS core network.
•
IPv6 Provider Edge Router support for IPv6 applications—Delivers IPv6 traffic over an IPv4/MPLS core with IPv6 provider edge router (6PE) support.
•
IPv6 VPN over MPLS (6VPE) support—Delivers IPv6 VPN over MPLS (IPv6) VPN traffic over an IPv4 or MPLS core with 6VPE support.
•
6VPE over L2TPv3 support—Delivers IPv6 VPN traffic over L2TPv3 core with 6VPE support (Cisco XR 12000 Series Router only). This feature is also available on Cisco IOS software.
•
Enhanced core competencies:
–
IP fast convergence with Fast Reroute (FRR) support for Intermediate System-to-Intermediate System (IS-IS)
–
Traffic engineering support for unequal load balancing
–
Path Computation Element (PCE) capability for traffic engineering
•
Firewall Services—Seamless insertion of Firewall Services in the data path with Virtual Firewall support on Multi Service Blade (XR-12K-MSB) for the Cisco XR 12000 Series Router.
•
VPN IPSec Aggregation —The IPSec Aggregation feature is provided through SPA-IPSEC-2G-2 card. The IPSec Aggregation feature allows you to terminate up to 64-K VPN tunnels, both site-to-site and remote access, if four VPN SPAs are used.
•
L2TPv3 Tunneling Mechanism—Service Providers who do not use MPLS in the core, but want to offer VPN services can use the L2TPv3 tunneling mechanism. This feature support includes IPv4 (VPNv4) and IPv6 (6VPE) VPN services using L2TPv3 encapsulation. The L2TPv3 packet is encapsulated in an IPv4 delivery header and is carried across an IPv4 backbone. VPN prefixes are advertised with BGP labels and resolved over L2TPv3 tunnels. This feature is supported only on the Cisco XR 12000 Series Router.
For more information about new features provided on various platforms for Cisco IOS XR Software Release 3.8.1, see the "New Software Features in Cisco IOS XR Software Release 3.8.1" section in this document.

New Software Features in Cisco IOS XR Software Release 3.8.1
The following sections contain information on new features and enhancements in Cisco IOS XR Software Release 3.8.1:
•
New Software Features Supported on All Platforms
•
Cisco CRS-1 Router-Specific Software Features
•
Cisco XR 12000 Series Router-Specific Software Features
New Software Features Supported on All Platforms
The following new software feature in Cisco IOS XR Software Release 3.8.1 is supported on both the Cisco CRS-1 and the Cisco XR 12000 Series Router:
•
LACP Short Period Time Intervals
Note
Cisco Session Border Controller (SBC) is not supported on any platform.
LACP Short Period Time Intervals
The Link Aggregation Control Protocol (LACP) Short Period Time Interval feature is supported in Cisco IOS XR Software Release 3.8.1 on the Cisco CRS-1 Router and Cisco XR 12000 Series Router.
Note
The Cisco XR 12000 Series Router also supports Packet-over- SONET (POS) bundled interfaces in Release 3.8.1.
LACP packets are exchanged periodically across bundle-member links to verify the link's stability and reliability. Configuring short period time intervals in which LACP packets are sent enables faster detection and recovery from link failures.
Note
On the Cisco XR 12000 Series Router, only the default short period (1000 milliseconds) is supported.
Short period time intervals are configured as follows:
•
In milliseconds
•
In increments of 100 milliseconds
•
In the range 100 to 1000 milliseconds
•
1000 milliseconds (1 second default)
•
Up to 64 member links
•
Up to 1280 packets per second (pps)
After six missed packets, the link is detached from the bundle.
When the short period time interval is not configured, LACP packets are transmitted over a member link every 30 seconds by default.
When the short period time interval is configured, LACP packets are transmitted over a member link once every 1000 milliseconds (1 second) by default. Optionally, both the transmit and receive intervals can be configured to less than 1000 milliseconds, independently or together, in increments of 100 milliseconds (100, 200, 300, and so on).
When you configure a custom LACP short period transmit interval at one end of a link, you must configure the same time period for the receive interval at the other end of the link.
Note
You must always configure the transmit interval at both ends of the connection before you configure the receive interval at either end of the connection. Failure to configure the transmit interval at both ends first results in route flapping (a route going up and down continuously). When you remove a custom LACP short period, you must do it in reverse order. You must remove the receive intervals first and then the transmit intervals.
Configuring the Default LACP Short Period Time Interval
This section describes how to configure the default short period time interval for sending and receiving LACP packets on a Gigabit Ethernet interface. This procedure also enables the LACP short period.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator.
Note
On the Cisco XR 12000 Series Router, only the default short period (1 second) is supported.
When you configure a custom LACP short period transmit interval at one end of a link, you must configure the same time period for the receive interval at the other end of the link.
Note
You must always configure the transmit interval at both ends of the connection before you configure the receive interval at either end of the connection. Failure to configure the transmit interval at both ends first results in route flapping (a route going up and down continuously). When you remove a custom LACP short period, you must do it in reverse order. You must remove the receive intervals first and then the transmit intervals.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator.
The lacp packet-capture command captures transmitted and received LACP packets on a single bundle member interface. The contents of these packets can then be displayed by the show lacp packet-capture command. If the lacp packet-capture command is not issued, the show lacp packet-capture command does not display any information.
The lacp packet-capture command continues capturing packets until the stop keyword is issued for that port or that bundle. Captured packets are stored and continue to be displayed until the clear keyword is issued for that port or that bundle.
Packets can be only captured for one port on a line card at a time. Starting a packet capture on a port implicitly stops and clears all packet captures on all other ports on that line card.
To stop capturing packets before the specified number of packets has been captured, issue the stop keyword.
If stop is specified for a single interface, packet capturing is stopped only on that interface.
If stop is specified for a bundle interface, packet capturing is stopped on all members of that bundle.
If stop is specified globally (the default—no parameters), packet capturing is stopped on all bundle interfaces on the router.
To clear all captured packets that are stored for an interface, issue the clear keyword.
If clear is specified for a single interface, packets are cleared only on that interface.
If clear is specified for a bundle interface, packets are cleared on all members of that bundle.
If clear is specified globally (the default—no parameters), packets are cleared on all bundle interfaces on the router.

Cisco CRS-1 Router-Specific Software Features
The following new features in Cisco IOS XR Software Release 3.8.1 are supported only on the Cisco CRS-1 platform:
•
Enhanced Process Distribution to Improve Load-Balancing Across Cisco CRS-1 RPs
Multicast Fabric Test
A new test, Multicast Fabric Test, has been added to the standard diagnostics tests as test number 11. There are no visible changes to the CLI. This test runs automatically with the standard diagnostics tests configured on the router or when the diagnostic start command is issued. This is supported on the Cisco CRS-1 Series Router.
Enhanced Process Distribution to Improve Load-Balancing Across Cisco CRS-1 RPs
This feature was introduced in Cisco IOS XR Release 3.6.3.
The default Cisco IOS XR process placement policy has changed to improve the distribution of processing load across active Cisco CRS-1 route processors (RPs). These changes affect systems with more than one active RP, such as Cisco CRS-1 multichassis systems and Cisco CRS-1 single-chassis systems with optional, distributed route processors (DRPs) installed.
Highlights of the New Process Distribution Feature
The new default process placement policy creates three groups of placeable processes:
•
Central Services and Infrastructure (CSI) group
•
IPv4 Routing/MPLS (IPv4) group
•
IPv6 Routing (IPv6) group
Each group is placed as a unit, with all processes within a group placed together on the same node.
The CSI group is, by definition, always placed on the dLRSC node. The only placement variation that can occur is in regard to the IPv4 and IPv6 groups.
If a single active non-dLRSC RP pair exists, the IPv4 and IPv6 groups are placed on that pair.
If more than one active non-dLRSC RP pair exists, the IPv4 group is placed on one such pair and the IPv6 group on another. The placement of each group occurs when that group starts.
If no non-dLRSC pairs exist, but an unpaired active non-dLRSC RP does, then, the first placeable group to start (IPv4/MPLS or IPv6) is placed on the dLRSC, with the other group being placed on the non-dLRSC RP pair.
Information About How Process Placement Works
•
An RP is considered paired for placement purposes if it was paired during system startup. This ensures that it is still considered to be paired even if the standby RP later becomes inactive. If a new pair was configured after system startup, you should perform a manual placement reoptimization to make sure that it is incorporated in the placement service. (See below.)
•
Process placement is SDR-scoped, occurring independently in each SDR.
•
Each DRP contains two processor complexes, CPU0 and CPU1, which are considered independent nodes by the placement service. For example, in a Cisco CRS-1 single-chassis system with two DRPs installed and configured as a pair, there are two non-dLRSC RP pairs, the CPU0 pair, and the CPU1 pair.
•
Tie-breaker rule—When determining placement for a group where multiple candidate nodes for the group, each of which satisfies the placement policy, exist, the candidates are ordered first by RP versus DRP (with the RP taking precedence), and then by node ID. The group is then placed at the first node in the resulting list.
•
RP failover events have no effect on process placement.
•
If an RP pair or an unpaired RP fails, any processes that were on the failed location migrate automatically to an active RP in accordance with the rules previously described. This would occur, for example, on Cisco CRS-1 multichassis systems when a rack online insertion and removal (OIR) take place.
•
No automatic placement changes occur as the result of a new node becoming active.
•
To redetermine placement of process groups based on the current state of the system, use the placement reoptimize command in EXEC mode.
Note
You should use the placement reoptimize command only during a maintenance window, because migrating routing processes between nodes may have a negative effect on traffic. However, to view the effects that a placement reoptimize command would have before you execute it, use the show placement reoptimize command.
•
Following an upgrade or downgrade of Cisco IOS XR software, you must execute the placement reoptimize command to make sure that process placement is consistent.
Cisco XR 12000 Series Router-Specific Software Features
The following new features in Cisco IOS XR Software Release 3.8.1 are supported only on the Cisco XR 12000 Series Router platform:
•
ATM Support for Layer 2 Tunnel Protocol Version 3 on Engine-5 Line Cards
Power Manager
The Power Manager software manages the following types of power requirements for the chassis components:
•
Type of power systems
•
Power supplies
•
Line cards installed in the chassis
•
Number of operational components in the chassis
With this software, newly discovered or inserted modules are prevented from powering up unless sufficient power is available to operate them.
The Power Manager software performs the following functions:
•
Sets the correct initial power manager state.
•
Identifies power supply number, type, power manager policy mode, and operational status to determine total available power and then accounts reserved chassis components.
•
Evaluates line cards for power-on, starting at the lowest numbered slots, and progressing upward until all slots are accounted for or available power is dropped below zero.
•
Minimizes added delay to chassis bootup or in the OIR insertion to LC usable time.
•
Performs a configuration check that generates warning messages or refuses to power up line cards if any of the configuration requirements are not met.
•
Determines the power available from the power shelf, predicts the maximum power required by all the chassis components, and uses this information to decide which components should be brought up during chassis bootup to remain within system power limits.
Note
Automatic fan speed control for thermal management is included with the Power Management feature to support the new blower modules with enhanced airflow cooling capacity.

Important Notes
•
Default timestamp setting—The timestamp prompt that precedes console output is enabled by default in Cisco IOS XR Software Release 3.8.1. To disable the timestamp prompt, use the timestamp disable command. For more information, see http://www.cisco.com/en/US/docs/ios_xr_sw/iosxr_r3.8/system_management/command/reference/yr38term.html#wp1311395.
•
For Cisco IOS XR Software Release 3.6.0 and later releases, WRED statements are collapsed, so that, if different random-detect statements using the same match types (EXP, DSCP, Prec, and so forth) are entered with identical minimum and maximum threshold values, a single configuration line is shown in the output of show running config. This reduces the length of the configuration, but creates a problem with backward compatibility with previous releases. In such a situation, on rollback, the QoS policy is rejected and must be manually entered again.

This can be done either by assigning at least 1 percent explicitly (bandwidth remaining percent 1) or by ensuring that the total bandwidth assigned to all other classes in the policy is a maximum of 99 percent, leaving 1 percent available for the class-default. A QoS policy that does not have any bandwidth for class-default is rejected when upgrading to Cisco IOS XR Software Release 3.6.0 or later releases.

Card, fan controller, and RP removal—For all card removal and replacement (including fabric cards, line cards, fan controller, and RP) follow the instructions provided by Cisco to avoid impact to traffic. See the Cisco IOS XR Getting Started Guide for procedures.
•
Exceeding Cisco testing—If you intend to test beyond the combined maximum configuration tested and published by Cisco, contact your Cisco Technical Support representative to discuss how to engineer a large-scale configuration maximum for your purpose.
•
More power required for Cisco SIP line cards (SIP-401/501/600/601) on the Cisco XR 12000 Series Router—These line cards draw more power than previous generation line cards. Depending on the exact configuration of power entry modules (PEMs) and other cards in the chassis, there may not be enough power available when inserting a new card or removing a PEM. Before you insert a new card or remove a PEM, run the following command in admin mode:
RP/0/0/CPU0:router# adminRP/0/0/CPU0:router# show environment power-supply table48V CurrentR/S/I Module (V) (A)0/24/* PEM1 54 4PEM2 53 40/25/* PEM1 54 4PEM2 53 4Total Power Supplies: 3200WRedundant Power Supplies: 1600WWorst Case Power Used: 621WCurrent Power Used: 428WCurrent Redundant Power Available: 1172WCurrent Total Power Available: 2772WWorst Case Redundant Power Available: 979WWorst Case Total Power Available: 2579WPID Description Watts--- ----------- -----GRP-B Route Processor 38PRP-1 Cisco 12000 Series Performance Route Processor 60LC-4OC-3-POS-SM 4 Port Packet Over SONET OC-3c/STM-1 804OC3X/POS-MM-MJ-B 4 port ISE OC3 90If you plan to insert a new card, locate the entry for the card to be inserted and note the power consumed by it. If this power is less than the figure given in Worst Case Redundant Power Available (the figure is displayed in the show environment power-supply table command output), the card can be safely inserted. As long as the Worst Case Redundant Power Available is not zero, a PEM can be powered down for replacement without impact.
Note
No alerts are issued if more cards are inserted than the PEMs can support. It is your responsibility to determine your power budget for the chassis before making any changes to it. Exceeding the power budget may result in the PEM being overloaded and cards powering down due to insufficient power being provided.
•
Per-interface Internet Control Message Protocol (ICMP) disable feature is not supported on Cisco XR 12000 Series Routers.
•
Online Diagnostics is not supported on the Cisco XR 12000 Series Router—If you execute the diagnostic command, an error appears stating that there is no online diagnostics process running on the router.
•
The rp mgmtethernet forwarding command is not supported on the Cisco XR 12000 Series Router.
•
mpls traffic engineering igp-intact command—This command must be used only when policy based tunnel selection is configured for all tunnels originating on the device.
•
L2TPv3 traffic is not supported on Ethernet bundle interfaces on the Cisco XR 12000 Series Router.
•
In Cisco IOS XR Release 3.8.1, the show running-config command includes an option to display the large configuration format. Using the formal option means that the output does not include submode indentations.
Minimum Flash Disk Requirements When Upgrading to Release 3.8.1
Cisco IOS XR Software Release 3.8.1 requires a 2-GB flash disk as a minimum, so if your Cisco CRS-1 or Cisco XR 12000 Series Router currently uses a 1-GB flash disk, you must upgrade it to 2-GB before upgrading to Cisco IOS XR Software Release 3.8.1.
The PCMCIA 1-GB flash disk was the default size for the Cisco CRS-1 running Cisco IOS XR Software Release 3.6 and earlier and for the Cisco XR 12000 Series Router running Cisco IOS XR Software Release 3.5 and earlier.
A 4-GB flash disk is available for both platforms and can be installed instead of the 2-GB for greater disk storage for Cisco IOS XR Software Release 3.4 and later.
To upgrade from a 1-GB flash disk to a 2-GB or greater flash disk, refer to the Cisco XR12000 and CRS-1 Flash Disk Upgrade Tasks document at http://www.cisco.com/en/US/docs/routers/xr12000/xr_line_cards/flashdisk/flashdisk.pdf.
Additional upgrade instructions for the Cisco CRS-1 router are available from http://www.cisco.com/web/Cisco_IOS_XR_Software/pdf/ReplacingPCMCIACardOnCRS-1.pdf.
Caveats
Caveats describe unexpected behavior in Cisco IOS XR software releases. Severity-1 caveats are the most serious.
The following caveats are open for Cisco IOS XR Software Release 3.8.1 on the router platforms indicated:
•
Caveats Specific to the Cisco CRS-1 Router
•
Caveats Specific to the Cisco XR 12000 Series Router
Caveats Specific to the Cisco CRS-1 Router
The following caveats are specific to the Cisco CRS-1 platform:
•
CSCta84988
Symptom:
Cisco CRS-1 systems might not reload successfully due to fabric planes remaining in MCAST DOWN state until manually recovered.
Description:
Occasionally on CRS-1 Multi-chassis systems with greater than 2 active planes the system may come up with one or more fabric planes in the MCAST DOWN state following a system reload.
The fabric plane state is found by issuing the show controllers fabric plane all admin command as shown in Example 1. If all odd or all even planes are in the MCAST DOWN state, the system does not come up and eventually reloads.
Example 1 Fabric Plane States in a Failed Condition
RP/0/RP0/CPU0:router# adminRP/0/RP0/CPU0:router(admin)# show controllers fabric plane allPlane Admin Oper up->dn Down Total DownId State State counter Flags Bundles Bundles------------------------------------------------------------0 UP MCAST_DOWN 0 m 27 181 UP UP 0 27 152 UP MCAST_DOWN 0 m 27 183 UP UP 0 27 154 UP UP 0 27 155 UP UP 0 27 156 UP UP 0 27 157 UP UP 0 27 15Conditions:
This issue might occur after a system reload.
Workaround:
None.
Recovery:
Use the following procedure to recover from this problem:
1.
Determine the affected planes by issuing the admin command admin show controllers fabric plane all.
The affected planes report the operating state as MCAST_ DOWN.
2.
Determine the affected S13 card in the affected plane.
Each line card chassis rack that is present in the system has an associated S13 card for each plane. For example, if a system that has three LCCs, the S13 cards for plane 0 are: 0/SM0/SP, 1/SM0/SP and 2/SM0/SP.
3.
Issue the following command for all SM cards in the affected plane:
show controllers backplane ethernet clients 25 statistics location [R]/sm[P]/sp]where:
[R] is for each rack in the system, and [P] is for each affected plane in the system.
The following example shows LCC0 if plane 0 is MCAST_DOWN:
show controllers backplane ethernet clients 25 statistics location 0/sm0/spRepeat this command for all LCCs for each affected plane.
4.
In the resulting display, look for the following line:
Rx mem score 264, alloc fails 0, free fails 0If the Rx mem score is 0 or any value other than 264, the card is OK.
If the Rx mem score is 264, this card is affected.
5.
Reload the affected S13 card by issuing the following admin command:
hw-module location [R]/SM[P]/SP reloadwhere:
[R] is the rack of the affected card and [P] is the affected plane.
For example, if 2/SM0/SP had an Rx mem score of 264, apply the following reload command:
admin hw-module location 2/SM0/SP reloadCisco IOS XR Caveats
The following caveats apply to both platforms:
•
CSCso32070
Basic Description:
ipv4_mfwd_partner: %ROUTING-IPV4_MFWD-5-IP_ADDR_RETRY
Symptom:
Multicast packets dropped.
Conditions:
This issue could happen due to SPA/LC OIR or commit replace.
After LC OIRed ARM updates to MFWD for non existent interface, MFWD attempts to update TYPE_ADD/TYPE_CHANGE for a non-existent interface handle. For these event types, MFWD checks with the IFH server to determine the interface type to see if this is a multicast supported interface.
The IFH server does not have any information for this OIRed interface. If this error occurs, ARM update for address does not process. The MFWD retries this failure every 30 seconds. The retry always fails since IFH does not know about the interface.
Workaround:
None.
Recovery:
Clear the mfib database location.
•
CSCsv00649
Basic Description:
Bundle members with LACP short flap once during RP fail over
Symptom:
Bundle members flap once and traffic loss occurs when LACP short is configured on members.
Conditions:
This issue occurs when RP FO with LACP short is configured on the members.
Workaround:
None.
Impact:
Traffic loss occurs during failover until the members come up. This issue does not have any impact on the router bring-up time.
Recovery:
No manual recovery is necessary. Traffic resumes automatically when the bundle members recover.

The following caveats are specific to the Cisco XR 12000 Series Router platform:
•
CSCsw25926
Basic Description:
Removing and adding back PRP-3 to a client LR results in its looped reset.
Symptom:
A PRP-3 RP resets continuously after using an SDR command to add the RP to a named SDR. The functionality of the owner SDR is not affected.
Conditions:
This issue occurs if a PRP-3 RP is removed from a named SDR and added back to the same SDR as part of the same commit.
For example, the router has the following configuration:
0/0/CPU0—Owner LR Active
0/1/CPU0—Owner LR Standby
0/2/CPU0—E5 LC in Owner
0/3/CPU0—Client LR1
0/4/CPU0—Client LR1
0/5/CPU0—E3 LC in LR1
The following command sequence causes 0/3 to start continuously resetting:
RP/0/0/CPU0:ios(admin-config)#logical-router lr1 RP/0/0/CPU0:ios(admin-config-lr:lr1)#loc 0/3/* RP/0/0/CPU0:ios(admin-config-lr:lr1)#no loc 0/3/* RP/0/0/CPU0:ios(admin-config-lr:lr1)#logical-router lr2 RP/0/0/CPU0:ios(admin-config-lr:lr2)#loc 0/3/* RP/0/0/CPU0:ios(admin-config-lr:lr2)#en Uncommitted changes found, commit them before exiting(yes/no/cancel)? [cancel]:yWorkaround:
Avoid triggering this issue by splitting the commit into two commits:
1.
In the first commit, remove the node from the first logical router.
2.
In the second commit, add the node to the second logical router.
Recovery:
To recover from the issue after it is triggered:
1.
Restart psarb and lrd on the DSC.
2.
Reload the entire router (owner and all client sdrs).
