Release Notes for Cisco 8000 Series Routers, IOS XR Release 25.4.1

BGP

Ease of Use

BGP Quick-withdraw

Introduced in this release on: Fixed Systems (8200 [ASIC: Q200, P100], 8700 [ASIC: P100, K100], 8010 [ASIC: A100]); Centralized Systems (8600 [ASIC: Q200]); Modular Systems (8800 [LC ASIC: Q100, Q200, P100])

BGP Quick-withdraw improves network responsiveness, reduces the risk of blackholing traffic, and maintains stable application performance during network events, such as nexthop failures or interface outages. It sends route withdraw messages as soon as bestpath computation determines that a prefix is unreachable.

The feature triggers early withdraws, allowing the remaining internal process, such as RIB deletion and label release, to continue in parallel. It is enabled by default for the supported address-families.

Previously, withdrawing unreachable routes was often delayed because BGP update generation waited for the entire prefix-processing pipeline to complete, including import, label allocation, and RIB installation.

Software Reliability

Policy-based cumulative bandwidth advertisements

Introduced in this release on: Fixed Systems (8200 [ASIC: Q100, Q200, P100], 8700 [ASIC: P100, K100], 8010 [ASIC: A100]); Centralized Systems (8600 [ASIC: Q200]); Modular Systems (8800 [LC ASIC: Q100, Q200, P100])

You can now reduce unnecessary BGP updates, such as frequent route advertisements caused by small, insignificant bandwidth changes, and improve network stability by suppressing minor bandwidth changes, rounding advertised bandwidth to a specified value, and setting outbound policy actions based on bandwidth thresholds.

Ease of Use

BGP per-link FRR for multipath backups

Introduced in this release on: Fixed Systems (8200 [ASIC: Q200]); Centralized Systems (8600 [ASIC: Q200]) ; Modular Systems (8800 [LC ASIC: Q100, Q200])

The feature enhances network resilience and accelerates convergence by allowing network operators to explicitly select a backup path for each primary next-hop. This approach ensures true path diversity and avoids common failure points, such as Shared Risk Link Groups (SRLG). It enables you to achieve convergence in approximately 50 milliseconds for prefixes, ensuring service continuity during primary link failures.

Previously, Fast Reroute (FRR) mechanisms like Prefix-Independent Convergence (PIC) automatically selected backup paths without explicit user control, which could lead to suboptimal path selection.

Software Reliability

Improved BGP-PIC convergence for multilink failures

Introduced in this release on: Fixed Systems (8200 [ASIC: Q200]); Centralized Systems (8600 [ASIC: Q200]; Modular Systems (8800 [LC ASIC: Q100, Q200])

The enhancement improves BGP-PIC convergence for multilink failures by aggregating multiple link-down events into a single hardware update to the FIB. This approach reduces hardware programming time required for FIB updates, speeds up recovery, and maintains network stability during clustered failures.

Previously, BGP-PIC processed each link failure one at a time, and each event triggered its own hardware update, which caused multiple hardware updates and longer convergence time.

EVPN

Software Reliability

EVPN ELAN automated-steering to flex-algorithms

Introduced in this release on: Fixed Systems (8100 [ASIC: Q200], 8200 [ASIC: Q200, P100], 8700 [ASIC: P100, K100], 8010 [ASIC: A100]); Centralized Systems (8600 [ASIC: Q200]); Modular Systems (8800 [LC ASIC: Q200, P100])

You can now automatically steer EVPN ELAN traffic onto paths computed by Segment Routing flex-algorithms. Flex-algorithms enable the definition of custom routing computations in the IGP (ISIS or OSPF) based on specific network constraints, such as minimizing latency or maximizing bandwidth. Automated-steering then applies policies to classify EVPN traffic and direct it to the appropriate Flex-algorithm path, ensuring that different types of EVPN services can utilize network resources optimally according to their requirements.

Software Reliability

EVPN ELAN services with SR-TE ODN, RT1, and RT3

Introduced in this release on: Fixed Systems (8100 [ASIC: Q200], 8200 [ASIC: Q200, P100], 8700 [ASIC: P100, K100], 8010 [ASIC: A100]); Centralized Systems (8600 [ASIC: Q200]); Modular Systems (8800 [LC ASIC: Q200, P100])

You can now enable dynamic traffic steering through SR-TE policy, improving traffic management by directing BUM and unicast traffic over optimized SR-TE paths. This capability is achieved by coloring route type 1 (RT1) and route type 3 (RT3) routes with a non-zero extended community color, which triggers traffic to follow the SRTE policy path instead of the default IGP path.

Software Reliability

EVPN E-Line with FXC service in VLAN unaware mode

Introduced in this release on: Fixed Systems (8200 [ASIC: P100], 8700 [ASIC: P100, K100], 8010 [ASIC: A100]); Modular Systems (8800 [LC ASIC: P100])

You can reduce BGP state complexity and improve scalability with EVPN E-Line in FXC VLAN unaware mode. This mode combines multiple normalized ACs on a single ES into one EVPN E-Line tunnel using a single service ID, advertising one EVI-EAD route per FXC instead of per AC. VLAN failures are not signaled over BGP. In multihoming, ES-EAD routes are present. However, if an AC fails on one PE, remote PEs are not notified, which may cause packet drops as traffic continues to be sent to the failed PE.

Software Reliability

Multisegment pseudowires

Introduced in this release on: Fixed Systems (8200 [ASIC: P100], 8700 [ASIC: P100, K100], 8010 [ASIC: A100]); Modular Systems (8800 [LC ASIC: P100])

You can improve network scalability and flexibility in delivering network services by extending Layer 2 services across multiple network segments through end-to-end stitching of several pseudowires. This capability simplifies service deployment and broadens network reach by allowing data to flow across multiple provider networks as a single virtual connection. This is made possible by linking multiple pseudowires in sequence, transporting Layer 2 frames across different segments without needing a direct pseudowire between endpoints.

IP Addresses and Services

Hardware Reliability

Egress hybrid ACL support

Introduced in this release on: Fixed Systems (8200 [ASIC: P100], 8700 [ASIC: P100]); Modular Systems (8800 [LC ASIC: P100])

Upgrade

Enhanced hashing functions using extended entropy profiles

Introduced in this release on: Fixed Systems(8200 [ASIC: Q200]);Modular Systems (8800 [LC ASIC: Q200])

This enhancement significantly reduces the risk of traffic polarization thus ensuring more even and efficient distribution of traffic across multiple network paths in large-scale networks.

This capability on certain user-defined header fields allows thousands of unique hash function selections.

Software Reliability

Egress hybrid ACL support to A100-based and K100-based ASICs

Introduced in this release on: Fixed Systems (8700 [ASIC: K100], 8010 [ASIC: A100])

You can now apply compression levels for object-group ACLs or hybrid ACLs to egress traffic on Cisco Silicon One K100-based and A100-based routers. This feature enables the router to accommodate additional ACLs or features and optimizes the usage of the TCAM space so that the available limited number of TCAM resources can be used efficiently.

Software Reliability

Extend support for ACLs on BVI to K100-based ASICs

Introduced in this release on: Fixed Systems (8700 [ASIC: K100])

You can now apply ACLs on Bridged Virtual Interfaces (BVIs) on Cisco Silicon One K100-based routers. This feature allows the router to block malicious traffic that targets the router. You can apply ACLs in both ingress and egress directions on a BVI.

Ease of Setup

Prior to this enhancement, error counters were spread across several CLI commands, making it difficult to assess FIB process health. This feature consolidates those metrics under a unified command.

Ease of Use

Enhanced ICMP error messages for traceroute

Introduced in this release on: Fixed Systems (8200 [ASIC: Q100, Q200, P100], 8700 [ASIC: P100, K100], 8010 [ASIC: A100]); Centralized Systems (8600 [ASIC:Q200]) ; Modular Systems (8800 [LC ASIC: Q100, Q200, P100])

This feature enhances the existing traceroute utility by adding detailed diagnostic information to ICMP error messages. Instead of just showing an IP address, traceroute can now display specifics about the incoming and outgoing interfaces and the next hop IP address at each hop. This provides deeper insights into the network path for troubleshooting.

Ease of Use

ICMP PROBE Utility

Introduced in this release on: Fixed Systems (8200 [ASIC: Q100, Q200, P100], 8700 [ASIC: P100, K100], 8010 [ASIC: A100]); Centralized Systems (8600 [ASIC:Q200]) ; Modular Systems (8800 [LC ASIC: Q100, Q200, P100])

This feature introduces a new network diagnostic tool called PROBE, similar to ping but with enhanced capabilities. It allows users to query the operational status of local interfaces or directly connected remote neighbors, providing details like Probe can report whether the interface is active, and whether IPv4 and IPv6 are running. PROBE operates via a proxy device, making it suitable for troubleshooting scenarios where direct bidirectional connectivity to the probed interface is not available.

Interface and Hardware Component

API Experience

Single UDP port for IPv4 and IPv6 packets

Introduced in this release on: Fixed Systems(8200 [ASIC: Q200])

BVI two-pass QoS ingress TC and EXP marking

Introduced in this release on: Fixed Systems (8200 Series [ASIC: P100], 8700 Series [ASIC: P100]) (select variants only*)

You can now apply consistent QoS treatment for traffic that moves from a bridge domain to a routed BVI. Your router performs two independent ingress QoS processing passes: it first classifies and marks traffic using Layer 2 attributes inside the bridge domain, and then applies a second Layer 3-based classification at the BVI ingress. At the BVI ingress, only traffic class (TC) or MPLS EXP marking actions are supported. This helps with accurate class assignment and predictable queuing for bridged-to-routed flows.

* This feature is supported on:
* 8212-48FH-M
* 8711-32FH-M

Software reliability

Security templates reduce misconfiguration risks and operational overhead by centralizing and standardizing security policy configuration for TLS-enabled applications. A security template bundles certificate authentication policy, TLS controls, and compliance mode settings. It acts as a single source of truth that applications reference, avoiding local embedding of security settings. This template defines how certificates are handled and controls various aspects of the TLS handshake.

Isolate Foreign Masters Causing Packet Timing Signal Fail

Introduced in this release on: Fixed Systems (8200 [ASIC: Q100, Q200, P100], 8700 [ASIC: P100, K100], 8010 [ASIC: A100]); Centralized Systems (8600 [ASIC:Q200]) ; Modular Systems (8800 [LC ASIC: Q100, Q200, P100])

This feature permits the flexible selection of timing sources by filtering out Foreign Master (FM) clocks that exhibit unstable timing. This filtering causes the secondary clocks to produce a signal deemed Packet Timing Signal Fail (PTSF)-unusable, from consideration within the Best Master Clock Algorithm (BMCA). The system continuously monitors these clocks for timing stabilization, and upon detecting enhanced stability, it may reevaluate and possibly reintegrate them as suitable time sources.

Software Reliability

PTP Phase Difference Threshold Between Passive and Secondary Ports

Introduced in this release on: Fixed Systems (8200 [ASIC: Q100, Q200, P100], 8700 [ASIC: P100, K100], 8010 [ASIC: A100]); Centralized Systems (8600 [ASIC:Q200]) ; Modular Systems (8800 [LC ASIC: Q100, Q200, P100])

Passive ports can now be included in the Delay Request-Response Mechanism (DRRM), which allows for the monitoring of PTP phase differences between a passive port and a secondary port. If these PTP phase differences surpass a predefined limit, system logs are triggered. This feature enables you to detect potential errors such as fiber asymmetry or a clock failure in the PTP network.
