What's New in Cisco IOS XR Release 7.2.2

Feature Description

Modular QoS

4K Pseudowire on bundle with QoS enhancement with min shaper value of 144 mbps

To enable hierarchical egress policies on the physical or on the virtual main interfaces with lower shaper values (lesser than 400 MB), use the hw-module profile qos physical-hqos-enable command.

QoS - Policer (48K/sys) & policy-map (6K/sys) scale enhancement

This feature is a QoS Policer scale enhancement on NCS560 with RSP4, which allows you to configure up to 24K policer per Core instead of 4K per core. In addition, the policy-map scale is also increased to 6K.

Segment Routing

DHCPv6 Relay Agent Support on SRv6

An IOS XR router can act as a DHCPv6 relay agent with a DHCPv6 server connected over an SRv6 network. A DHCP relay agent is a host that forwards DHCP packets between clients and servers that do not reside on a shared physical subnet.

SRv6 Flexible Algorithm for IS-IS

This feature allows operators to customize IGP shortest path computation according to their own needs. An operator can assign custom SR prefix-SIDs to realize forwarding beyond link-cost-based SPF. As a result, Flexible Algorithm provides a traffic engineered path automatically computed by the IGP to any destination reachable by the IGP. The SR architecture associates prefix-SIDs to an algorithm which defines how the path is computed. Flexible Algorithm allows for user-defined algorithms where the IGP computes paths based on a user-defined combination of metric type and constraint.

SRv6 OAM — SID Verification

This feature provides enhanced Operations, Administration, and Maintenance (OAM) in Segment Routing Networks with IPv6 Data plane (SRv6). Existing OAM mechanisms to ping and trace a remote IPv6 prefix, along the shortest path, continue to work without any modification in an SRv6 network. However, classic IPv6 OAM cannot be used to ping or trace a remote SRv6 SID function. This feature augments ping and traceroute operations to target remote SRv6 SIDs. An SRv6-enabled router now allocates a new SRv6 OAM SID known as END.OP (OAM Endpoint with Punt).

SRv6 Services: BGP Global IPv6

This feature extends support of SRv6-based BGP services to include Internet (IPv6) services by implementing End.DT6 SRv6 functions at the PE node.

SRv6 Services: EVPN VPWS — All-Active Multi-Homing

This feature provides an ELINE (P2P) service with all-active multihoming capability over an SRv6 network. All-Active Multi-Homing enables an operator to connect a customer edge (CE) device to two or more provider edge (PE) devices to provide load balancing and redundant connectivity. With All-Active Multi-Homing, all the PEs can forward traffic to and from the multi-homed device.

SRv6 Services: IPv6 L3VPN

This feature provides support for IPv6 L3VPNs (VPNv6) over an SRv6 network SRv6-based L3VPN uses SRv6 Segment IDs (SIDs) for service segments instead of labels. SRv6-based L3VPN functionality interconnects multiple sites to resemble a private network service over public infrastructure.

ISSU

ISSU Support on NCS560 CFP2 DCO IM

The ISSU feature is now supported on the NCS560 CFP2 DCO interface module.

L2VPN

VPLS over BGP LU with or without PIC over ISIS or OSPF SR

This feature enables VPLS across inter-AS through BGP LU while Segment Routing is enabled in the core. This feature functions independent of BGP PIC. This feature is supported on Cisco NCS 560 routers.

Behavior Change Introduced in this Release

Behavior change refers to any modification of an existing software feature, configuration, or a command. This release introduces following behavior change:

Guidelines for Enabling FIPS

You must follow these guidelines while enabling FIPS mode:

  • You must configure the session with a FIPS-approved cryptographic algorithm. A session configured with non-approved cryptographic algorithm for FIPS (such as, MD5 and HMAC-MD5) does not work. This is applicable for OSPF, BGP, RSVP, ISIS, or any application using key chain with non-approved cryptographic algorithm, and only for FIPS mode (that is, when crypto fips-mode command is configured).

  • If you are using any HMAC-SHA algorithm for a session, then you must ensure that the configured key-string has a minimum length of 14 characters. Otherwise, the session goes down. This is applicable only for FIPS mode.

  • If you try to execute the telnet configuration on a system where the FIPS mode is already enabled, then the system rejects the telnet configuration.

  • If telnet configuration already exists on the system, and if FIPS mode is enabled later, then the system rejects the telnet connection. But, it does not affect the telnet configuration as such.

  • It is recommended to configure the crypto fips-mode command first, followed by the FIPS-related commands in a separate commit. The list of commands related to FIPS with non-approved cryptographic algorithms are:

    • key chain key-chain-name key key-id cryptographic-algorithm MD5

    • key chain key-chain-name key key-id cryptographic-algorithm HMAC-MD5

    • router ospfv3 1 authentication ipsec spi 256 md5 md5-value

    • router ospfv3 1 encryption ipsec spi 256 esp des des-value

    • router ospfv3 1 encryption ipsec spi 256 esp des des-value authentication md5 md5-value

    • snmp-server user username usergroup-name v3 auth md5 priv des56

    • ssh server algorithms key-exchange diffie-hellman-group1-sha1

    • telnet vrf default ipv4 server max-servers server-limit

PSU Redundancy Lost Alarm:

PSU redundancy lost alarms are generated when there is no proper input feed applied on any one of Power Modules (PMs) (PM0 or PM1). The alarms are also generated when the output for PM0 or PM1 is not proper.

The following alarms are raised for PSU redundancy lost event with a faulty PM0:

  • Power Module Generic Fault

  • Power Module Error

  • Power Group Redundancy Lost

This is applicable to the following routers with fixed PSUs:

  • N540-28Z4C-SYS-A/D

  • N540X-16Z4G8Q2C-A/D

  • N540-12Z20G-SYS-A/D

  • N540X-12Z16G-SYS-A/D

  • N540X-6Z18G-SYS-A/D

  • N540X-8Z16G-SYS-A/D

  • N540X-4Z14G2Q-A/D

Caveats

This section describes open and resolved severity 1 and 2 caveats and select severity 3 caveats:

  • The “Open Caveats” sections list open caveats that apply to the current release and may apply to previous releases. A caveat that is open for a prior release and is still unresolved applies to all future releases until it is resolved.

  • The “Resolved Caveats” sections list caveats resolved in a specific release, but open in previous releases.

The bug IDs are sorted alphanumerically.


Note

The Caveats section includes the bug ID and a short description of the bug. For details on the symptoms, conditions, and workaround for a specific caveat you must use the Bug Search Tool.
