Cisco ASR 9000 Series Routers, IOS XR Release 26.2.1
Cisco ASR 9000 Series Routers, IOS XR Release 26.2.1
Cisco IOS XR Release 26.2.1 introduces comprehensive enhancements for ASR 9000 Series routers, focusing on network agility, security, and operational scalability. Key updates include P-BNG and cnBNG coexistence for seamless migration, expanded IPv4 and dual-stack support for routed subscriber sessions, and multiple control plane associations for improved cnBNG redundancy. Operational efficiency is bolstered by regex-based filtering for MPLS-TE, SRv6 load-balancing via source address entropy, and VRF-specific BFD multipath assignment. Security is strengthened by moving deprecated protocols like Telnet and FTP to optional RPMs, while licensing is streamlined via Smart Licensing for 8011-PE variants. Additionally, nV Satellite capabilities are significantly expanded with support for new 8000 Series hardware, bundle load-balancing auto mode, cross-layer QoS enforcement, MD5 authentication for ICCP links, and high-speed ICL support up to 400GbE, collectively optimizing high-scale WAN and metro aggregation deployments.
Table 1. New software features for ASR 9000 Series Aggregation Services Routers, Release 26.2.1
| Product impact |
Feature |
Description |
| BNG |
||
| Software Reliability
|
Enhances network agility and migration efficiency by enabling the simultaneous operation of physical BNG and Cloud-Native BNG (cnBNG) on a single router. This feature provides a flexible mechanism for a phased transition with minimal disruption to cloud-native architectures, supporting interface-level configuration exclusivity, service continuity, and unified subscriber management across hybrid deployments. |
|
| Cloud Native BNG User Plane |
||
| Software Reliability
|
You can now improve cnBNG redundancy and flexibility by enabling a single User Plane (UP) to connect to multiple Control Plane (CP) instances at the same time. This allows Subscriber Redundancy Groups (SRG) to be mapped more flexibly across different CPs. |
|
| Software Reliability
|
We have enhanced this feature to support IPv4, and dual-stack routed subscriber sessions, including on bundle-ether VLAN interfaces, which improves scalability and deployment flexibility in Layer 3 access networks. Previously, only IPv6 was supported. |
|
| Licensing |
||
| Licensing process
|
Support for Smart Licensing Using Policy
|
Cisco Smart Licensing Using Policy streamlines the licensing process for Cisco IOS XR products. You no longer need to register your device during installation, and there is no evaluation license state or period. Smart Licensing support is now extended to the ASR 9000 host with the following port extender variants: • 8011-4G24Y4H-I-SAT • 8011-32Y8L2H2FH-SAT |
| MPLS |
||
| API experience
|
This feature enhances operational scalability and usability by allowing regex-based tunnel name filtering for MPLS‑TE show and execution commands, without changing configuration models, architecture, or security posture. This feature supports regular expression in all MPLS-TE show and execution commands using tunnel names. |
|
| Routing |
||
| Software Reliability
|
This feature allows you to pin BFD MP sessions to specific LCs by associating a destination IP and VRF with a physical location. When configured, the system automatically migrates matching sessions to the designated LC. This prevents collateral service disruption for unrelated tenants by ensuring that an LC reload only impacts sessions pinned to that specific hardware. |
|
| Segment Routing |
|
|
| Ease of Use
|
SRv6 Flow Label entropy via source address
|
This feature improves SRv6 load balancing by encoding entropy from the IPv6 flow label into the IPv6 source address during SRv6 encapsulation. With this enhancement, the ingress node generates a flow-aware Ipv6 source address. This allows downstream devices to use standard IP-based hashing for consistent ECMP load balancing. This feature uses the modified source address for hashing, ensuring effective end-to-end load balancing even when the IPv6 flow label is ignored. Previously, SRv6 relied on Flow Label–based entropy for load balancing. However, some backbone nodes especially in cloud environments ignore the Flow Label. This caused traffic polarization and inefficient bandwidth utilization. The feature introduces these changes: CLI: • The add-entropy flow-label position keyword is introduced in the srv6 encapsulation command. |
| Setup and Upgrade |
||
| Upgrade
|
This feature improves platform security and reduces the threat surface of the Cisco Networking products by restricting insecure protocols such as Telnet, FTP, TFTP, and RCP (which were deprecated in Cisco IOS XR Release 25.4.1) from Cisco IOS XR base package. In this release, Telnet is added to the optional RPM, {{Telnet.rpm}}, and FTP, TFTP, and RCP are added to the optional RPM, {{IP-Insecure-Apps.rpm }}. We recommend you to migrate to secure alternatives such as SSH, SCP, SFTP as Telnet, FTP, TFTP, and RCP protocols will not be supported anymore starting from an upcoming Cisco IOS XR release. |
|
| nvSatellite |
||
| Hardware Reliability
|
Cisco ASR 9000 Series hosts now support the Cisco 8011-32Y8L2H2FH and Cisco 8011-4G24Y4H-I as satellite devices. This expands the satellite portfolio by introducing new Cisco 8000 Series platforms that can be deployed with the ASR 9000 host for satellite-based access and aggregation. These new satellites provide greater deployment flexibility, support high-density and high-speed interface options, and help optimize network scaling based on different port and bandwidth requirements. This allows users to extend ASR 9000 host capabilities while simplifying operational management across satellite deployments. |
|
| Software Reliability
|
Bundle interface load-balancing auto mode for nV Satellite ICL |
You achieve predictable, per-port traffic forwarding on nV Satellite Inter Chassis Link (ICL) bundles by automatically mapping each satellite access port to a specific host bundle member. This ensures consistent policing and simplifies troubleshooting by overriding dynamic load-sharing and pinning all traffic from each port to dedicated hardware. |
| Software Reliability
|
You can now match and enforce QoS policies using L3 fields, such as DSCP and IP address on L2 interfaces, and L2 fields, such as CoS on L3 interfaces. This enables consistent QoS policy enforcement across your network boundaries without manual mode switching; simply apply your policy and the system handles cross-layer matching. |
|
| Software Reliability
|
You can enable MD5 password authentication for ICCP links in dual home mode by configuring the neighbor password command in MPLS LDP configuration mode. This secures TCP communication between hosts by generating and verifying MD5 checksums on messages. Both neighbors must have matching passwords for the session to establish successfully. This feature enhances link security and ensures reliable communication. |
|
| Software Reliability
|
Support for 10GbE, 100GbE, and 400GbE Inter-Chassis Links on Cisco 8000 Series Satellites |
Starting from Cisco IOS XR Release 26.2.1, Cisco 8000 Series satellites support 10GbE, 100GbE, and 400GbE Inter-Chassis Links (ICLs). This feature introduces configurable ICL and access port speed combinations for the Cisco 8011-32Y8L2H2FH satellite, along with default 4x100GbE ICL support on the Cisco 8011-4G24Y4H-I satellite. It provides greater flexibility in satellite deployment by allowing you to choose port-speed combinations that align with different network design and bandwidth requirements. This helps optimize connectivity between the host and satellite while supporting a range of access interface speeds. |
| Software Reliability
|
Support for 1GbE, 10GbE, 25GbE access port speed Cisco 8000 Series Satellites |
Starting from Cisco IOS XR Release 26.2.1, Cisco 8000 Series satellites support 1GbE, 10GbE, and 25GbE access port speed. This feature introduces configurable access port speed combinations for the Cisco 8011-32Y8L2H2FH satellite, along with default 4x100GbE ICL support on the Cisco 8011-4G24Y4H-I satellite. It provides greater flexibility in satellite deployment by allowing you to choose port-speed combinations that align with different network design and bandwidth requirements. This helps optimize connectivity between the host and satellite while supporting a range of access interface speeds. |
New hardware
There is no new hardware introduced in this release.
● Remove of Model-driven CLI Commands: Starting from Cisco IOS-XR software release 26.2.1, the Model-driven CLI specifically the show YANG operational data commands have been removed.
● SNMP Traps Dropped in the Buffer Queue: Starting with IOS-XR software release 24.1.2, SNMP traps will be dropped from the trap queue during the first five minutes after configuring a new NMS server or after a device reload.
◦ This issue is observed on all current releases of the Cisco IOS XR routers running IOS XR Release 24.1.2.
◦ The defect applies only to NMS servers that are located behind a firewall or within a security network where ICMP packets are blocked.
● Updated Command Syntax and Usage Guidelines
● As an enhancement to the show cef commands, the internal, brief, and hardware keywords have been removed from these commands:
◦ show cef unresolved
◦ show cef ipv6 linklocal unresolved
● The internal and brief keywords have been removed from these commands:
◦ show cef mpls unresolved
◦ show cef mpls local-label
● Exceptions
◦ This command retains support for the internal and brief keywords when a specific prefix is provided: show cef unresolved
◦ Usage Constraints for show cef mpls: When executing any command beginning with show cef mpls, you may use only one of these keywords at a time: brief, detail, or internal
◦ Note: The exception mentioned above applies: if the command includes unresolved or local-label, the internal and brief keywords are explicitly blocked.
● Change in forwarding information base manager identifier reporting: Previously, all forwarding information base manager (fib_mgr) instances across different locations—such as the Route Processor (RP) and Line Cards (LCs)—shared the same identifier, fib_mgr. Consequently, the show command output displayed only a single entry for application fib_mgr.
● With this update, each fib_mgr instance is assigned a unique identifier corresponding to its specific location. As a result, the show route afi-all summary command now lists all instances individually. For example, the output will display fib_mgr for the RP and FIB node0_3_CPU0 for the LC located at node0_3_CPU0.
● Manual Remediation of Forward-Referenced SRLG Interfaces: The existing Shared Risk Link Groups (SRLG) feature allows configuring SRLG values on interfaces that do not yet exist (forward-reference interfaces). These configurations appear in the output of the show srlg command. To avoid inconsistencies, manually remove all SRLG configurations related to non-existent or forward-referenced interfaces. This manual cleanup is essential to maintain system consistency and prevent misleading information in the SRLG display.
● Enhanced MPLS interface activation for IS-IS address-family lifecycle events: Starting with Cisco IOS XR Release 26.2.1, IS-IS enables or disables MPLS on an interface when the first or last MPLS-enabled address family is created or deleted, instead of waiting for operational UP or DOWN state transitions. Previously, MPLS state changes occurred only during interface shutdown or link-down events. With this enhancement, MPLS state updates now also occur when the interface configuration is removed at the root level or when the last IPv4 or IPv6 address associated with an MPLS-enabled address family is removed from the interface.
● MPLS-TE tunnel event history for insufficient bandwidth events: Starting with Cisco IOS XR Release 26.2.1, MPLS-TE tunnel events for insufficient bandwidth conditions are recorded in the tunnel event history. Previously, when a tunnel failed to reoptimize because the requested bandwidth was unavailable, the router generated syslog messages, but the event was not shown in the show mpls traffic-eng event-history tunnels output. This update adds a tunnel event for insufficient bandwidth so that you can review historical bandwidth-demand failures for debugging and capacity planning.
● Mandatory LDAP TLS Validation: LDAP server certificate validation for TLS connections is now enabled by default. Unlike previous versions that skipped validation when no trustpoint was defined, the current implementation mandates the use of a configured ldaps trustpoint to establish a secure connection. If this trustpoint is absent, the connection is automatically rejected, ensuring that all LDAP traffic is strictly authenticated and verified.
● These behaviors apply based on the configuration of the ldaps trustpoint:
◦ No trustpoint configured: The TLS connection to the LDAP server is rejected by the router.
◦ CA certificate only: The router uses the configured CA certificate to validate the LDAP server's certificate; the connection is established only upon successful validation.
◦ CA and client certificate configured: The router uses the CA certificate to validate the server's certificate while presenting the client certificate to satisfy mTLS requirements; the connection is established only if both validation checks pass.
● MACsec Licensing Tier Update: Effective with Cisco IOS XR Software Release 26.2.1, MACsec on Cisco IOS XR routers utilizing the FCM 2.0 Access licensing model now requires the Advantage tier instead of the Premier tier. When MACsec is enabled on a physical interface, the interface bandwidth triggers Right-to-Use (RTU) consumption for the Access Advantage tier, calculated in 10G increments. This license consumption is reclaimed once the MACsec configuration is removed or the interface is shut down.
● Deprecated Security Algorithms: Starting Cisco IOS XR Release 26.2.1, the 3DES-CBC cipher and Diffie-Hellman Group 1 SHA1 key exchange are insecure and deprecated. You will see syslog warning messages for deprecated commands.
● Change in show media CLI output: The directory path previously shown as /var/lib/docker now appears as apphost in the show media CLI output. This change enhances clarity for users managing third-party applications and Docker containers. It also accurately reflects the directory’s role within the Cisco IOS XR application hosting architecture.
● A deprecation notice is shown when you run the show tech-support netconf command.
● Starting Cisco IOS XR Release 26.2.1, you can set the ipv6 nd ns-interval value to less than 60 seconds on these virtual interfaces:
◦ Bundle Ethernet interfaces
◦ BVI interfaces
◦ Pseudowire Ethernet interfaces
● NACM show command visibility improvements: Starting from Release 26.2.1, you get better visibility of NACM rules and groups in show nacm command outputs when dynamic NACM is used. This enhancement improves how information is displayed without changing existing functionality, ensuring NACM rules continue to operate as before.
● Enhanced syslog reporting for discard-extra-paths limits: Starting in Release 26.2.1, syslog notifications for the discard-extra-paths limit have been enhanced to provide per-neighbor and per-address-family reporting. This replaces the previous global notification behavior, which applied a 5-minute rate limit across the entire BGP process. The updated notifications are rate-limited to 30 seconds and reset automatically if the neighbor session flaps.
● LOS Alarm Based on Total Power Support: Starting with IOS-XR software release 26.1.1, a new Loss of Signal (LOS) alarm based on total received power has been introduced.
Alarm Behavior
o The existing payload-based LOS alarm has been renamed to LOS-P to accurately reflect its function.
o Automation scripts and operational procedures that previously relied on the old LOS alarm may misinterpret alarms if not updated.
