What's New in Cisco IOS XR Release

Cisco is continuously enhancing the product with every release and this section covers a brief description of key features and enhancements. It also includes links to detailed documentation, where available.

Table 1. New Software
Feature Description

BGP

Additonal path control per neighbor

This features allows flexibility and granular control of the advertisement of additional paths based on the neighbor outbound policy configuration.

This is done by allowing configuration of combinations diff erent path selection procedures unlike singular path selection, and extending neighbor outpound policy to have finer control of the path types to be advertised.

This feature enables operational efficiency to manage additional paths and reduce scale of the paths in a typical clustered network architecture.

Without this feature, the path scale limitation of the memory is impacted, and control plane convergence issues develop because of the excessive number of paths.

BGP FlowSpec Actions

This feature provides information on the actions that can be associated with a BGP flow. The traffic filtering flow specification is applied based on the specified rule. The following extended community values that can be used to specify particular action:

  • Set DSCP

  • Redirect IPv4 or IPv6 Nexthop

BGP FlowSpec NLRI types

A BGP flow specification consists of several matching criteria encoded in the NLRI that is applied to IP traffic. A given IP packet must match all the specified criteria. Network layer reachability information (NLRI) exchanges routing information and matching criteria between BGP peers, indicating how to reach the destination.

The following NLRI types are supported:

  • Type 7: IPv4 or IPv6 ICMP type

  • Type 8: IPv4 or IPv6 ICMP code

  • Type 9: IPv4 TCP flags (2 bytes include reserved bits)

  • Type 10: IPv4 Packet length

  • Type 11: IPv4 or IPv6 DSCP

  • Type 12: IPv4 or IPv6 fragmentation bits

Routing

Conditional Static Anycast Route Advertisement

This feature enables you to to detect core isolation and improve network convergence. The conditional installation of static route in routing table (RIB) based on object state functionality has been enhanced to use event driven notification, instead of the polling mechanism used earlier. This event driven approach allows faster detection and notification of object state changes. This feature along with BGP Neighbor address-family tracking, allows users to detect network faults quicker and take corrective action faster.

This feature improves network convergence and reduces, and in some cases, eliminates traffic outages in the event of certain network faults, such as either link or node failures or both. Without this new feature, it will take longer to detect network faults and increase the duration of network outage.

System Security

MACsec capability for 88-LC0-36FH-M

The Cisco 8800 36x400GE QSFP56-DD Line Card with MACsec based on Q200 Silicon (88-LC0-36FH-M) supports point-to-point (P2P) MACsec capability with 400GE line rate encryption on its physical interfaces.

This release also introduces point-to-multipoint (P2MP) MACsec capability on both 8800-LC-36FH-M and 8800-LC-48H (Cisco 8800 48x100 GbE QSFP28 Line Card based on Q100 Silicon). The P2MP topology connects multiple nodes to one central node, thereby avoiding unnecessary packet replication at the ingress router.

uRPF in Loose Mode with allow-default

When the source IP address of an incoming packet is not present in the Forwarding Information Base (FIB), the router considers it as an invalid packet and drops it. Use the allow-default keyword of ipv4/ipv6 verify unicast source reachable-via command and configure the default route for the interface so that the router does not drop a packet even when the source IP address is not present in the FIB.

The command ipv4/ipv6 verify unicast source reachable-viais introduced.

System Monitoring

Message Logs for Third-Party Software Containers

This feature introduces the logging container all command to monitor messages from a third-party container logs, such as Docker.

System Management

Dynamic Power Management

The Dynamic Power Management feature considers certain dynamic factors before allocating power to the fabric and line cards.

This feature has the following benefits:

  • Reduces number of PSUs required by accurately representing the maximum power consumption

  • Improves PSU efficiency by providing more accurate power allocation

This feature thus optimizes power allocation and avoids overprovisioning power to a router.

NPU Power Optimization

This feature lets you choose a predefined NPU power mode based on your network's individual requirements, and consequently reducing NPU power consumption.

The hw-module npu-power-profile command is introduced for this feature.

Interface and Hardware Component

1023 Ethernet Bundle Interfaces Support

With the introduction of this enhancement, the maximum system-wide bundle interface scale has increased from 512 to 1023 bundle interfaces. The default value remains at 64-member links for each bundle.

64-bit Bandwidth Support

With this release, the Cisco 8000 Series Router supports 64-bit bandwidth field, as opposed to the previous 32-bit bandwidth field. 64-bit bandwidth enables the system to support interface bandwidths greater than 4.2T.

CFM on Bundle Member Link for Connectivity Check

This feature introduces support for Connectivity Fault Management (CFM) on bundle members. Earlier, network administrators managed networks by using the fault, configuration, account, performance, security model. CFM is one of a suite of the Ethernet OAM protocols, which uses a combination of keepalive packets and MAC-based pings, and traceroutes to detect faults in a network.

With the CFM feature, you:

  • reduce operating expenses for service operators by reducing network faults and errors

  • provide end-to-end maintenance of networks

Up MEP and Down MEP Support in CFM

This feature introduces Maintenance End Points (MEP) entities that you can configure in a domain.

MEPs send either CFM frames from the interface where they are configured or CFM frames that are received on other interfaces.

MEPs allow you to perform fault management and carry out performance checks.

IP Addresses and Services

IPv6 Extension Headers in Hybrid ACLs

You can configure ingress IPv6 hybrid ACLs with compression level 2 to permit or deny packets on the basis ofIPv6 extension headers set in them. IPv6 extension headers include routing headers, authentication headers, and destination option headers. These extension headers contain information that is used by network devices (routers and switches) to route or process an ingress IPv6 packet.

The ipv6 access-group command is modified.

TCP Flags in Egress IPv6 ACLs

You can configure an egress IPv6 ACL that permits or denies packets on the basis of TCP flags set in them. Through this feature, you can restrict and manage traffic streams thereby enhancing network security.

The following commands are updated:

Multicast

MFIB scale enhancement

This feature allows you to increase the route-scale for IPv4 SSM from 64K to 120K using the hw-module multicast route-scale command.

mLDP Loop-Free Alternative Fast Reroute

When this feature is enabled, mLDP relies on the Loop-Free Alternative algorithm to calculate the primary and backup, which is also referred as fast re-route path. During the event of a link failure, the router uses this precomputed backup path to send the multicast traffic. The fast switchover helps to reduce multicast traffic loss and the switchover time is less than 50 milliseconds.

Modular QoS

Priority Flow Control

This feature and the hw-module profile priority-flow-control command are supported on 88-LC0-36FH-M and 8800-LC-48H line cards.

Priority Flow Control Support on Cisco 8800 36x400 GbE QSFP56-DD Line Cards (88-LC0-36FH-M)

The Cisco 8800 36x400 GbE QSFP56-DD Line Card (88-LC0-36FH-M) supports the Priority Flow Control feature. All previous functionalities and benefits of this feature are available on these line cards. However, the buffer-internal mode is not supported.

In addition, to use the buffer-extended mode on these line cards, you are required to configure the performance capacity or headroom values. This configuration requirement ensures that you can better provision and balance workloads to achieve lossless behavior, which in turn ensures efficient use of bandwidth and resources.

QoS Policy Inheritance

To create QoS policies for subinterfaces, you had to apply the policy on each subinterface manually. From this release, all you do is create and apply a single QoS policy on the main interface and the subinterfaces automatically inherit the policy.

The inheritance model provides an easily maintainable method for applying policies, enabling you to create targeted policies for a group of interfaces and their subinterfaces. This model saves your time and resources while creating QoS policies.

L2VPN

Inter-AS Mode for L2VPN Pseudowire

Inter-AS is a peer-to-peer type that allows VPNs to operate through multiple providers or multi-domain networks using L2VPN cross-connect. This mode allows VPLS autodiscovery to operate across multiple BGP autonomous systems and enables service providers to offer end-to-end VPN connectivity over different geographical locations.

Load Balance MPLS PW Traffic using Control-Word

This feature allows the router to correctly identify the Ethernet PW packet over an IP packet, thus preventing the selection of wrong equal-cost multipath (ECMP) path for the packet that leads to the misordering of packets. This feature inserts the control word keyword immediately after the MPLS label to separate the payload from the MPLS label over a PW. The control word carries layer 2 control bits and enables sequencing.

The control-word keyword is added.

Load Balance MPLS PW Traffic using Flow-Label

The flow-label provides the capability to identify individual flows within a pseudowire and provides routers the ability to use these flows to load balance traffic. Individual flows are determined by the hashing algorithm configured under L2VPN. Similar packets with the same source and destination addresses are all said to be in the same flow. A flow-label is created based on indivisible packet flows entering a pseudowire and is inserted as the lowermost label in the packet. Routers can use the flow-label for load balancing which provides a better traffic distribution across ECMP paths or link-bundled paths in the core.

The flow-label keyword is added.

Pseudowire VC Type 4

With this feature, VLAN mode is supported for pseudowire over MPLS. A virtual connection (VC) type 4 is the VLAN-based PW. The ingress PE does not remove the incoming VLAN tags that are to be transported over the PW. VC type 4 inserts an extra dummy tag with VLAN 0 onto the frame which is removed on the other side. This mode helps the service provider to segregate traffic for each customer based on the VLAN.

Pseudowire VC Type 5

With this feature, Ethernet port mode is supported for pseudowire over MPLS. The virtual connection (VC) type 5 is known as an Ethernet port-based PW. In this mode, both ends of a pseudowire are connected to Ethernet ports and allow a complete ethernet trunk to be transported. The ingress PE transports frames received on a main interface or subinterface. This feature nullifies the need for a dummy tag and reduces overhead. In addition, frame tagging is no longer necessary.

Pseudowire over MPLS

This feature allows you to tunnel two L2VPN Provider Edge (PE) devices to transport L2VPN traffic over an MPLS core network. MPLS labels are used to transport data over the pseudowire.

Support of Tagged or Untagged VLAN on Physical and Bundle AC with VLAN Rewrite

This feature supports tagged or untagged VLAN on physical and bundle interfaces. The tagged VLAN allows you to send and receive the traffic for multiple VLANs whereas, the untagged VLAN allows you to send and receive the traffic for a single VLAN. The multiple VLANs are used to differentiate traffic streams so that the traffic can be split across different services.

L3VPN

Carrier Supporting Carrier for L3VPN

This feature enables MPLS VPN-based backbone carriers to allow customer carriers to use a segment of the backbone network. The backbone carrier can accommodate many customer carriers and provide access to the backbone. Customer carriers no longer have to bear the burden of configuring, operating, and maintaining their own backbone.

To know about all the RPMs installed including XR, OS and other components use the show install active all command.

The software modularity approach provides a flexible model that allows you to install a subset of IOS XR packages on devices based on your individual requirements. All critical components are modularized as packages so that you can select the features that you want to run on your router.


Note


The above show command output displays mandatory packages that are installed on the router. To view the optional and bug fix RPM packages, first install the package and use the show install active summary command.

Other Important Information

  • The warning message that the smart licensing evaluation period has expired is displayed in the console every hour. There is, however, no functionality impact on the device. The issue is seen on routers that don’t have the Flexible Consumption licensing model enabled. To stop the repetitive messaging, register the device with the smart licensing server and enable the Flexible Consumption model. Later load a new registration token.

    To register the device with the smart licensing server, see the Registering and Activating Your Router.
