Cisco ASR 9000 Series Routers, IOS XR Release 26.3.1
Cisco ASR 9000 Series Routers, IOS XR Release 26.3.1
Cisco IOS XR Release 26.3.1 for Cisco ASR 9000 Series Routers introduces robust enhancements across architecture, routing, security, and operational simplification. Architectural scalability is advanced with Enhanced monitoring capability supporting 128k GRE tunnels, static pseudowires, and L2 transport interfaces, while persistent logging preserves syslog continuity across reloads and failovers. Routing reliability improves with eBGP RT-constraint multipath for resilient VPN route propagation, inter-area route propagation limits in IS-IS, and gNMI Internal Path sharing for optimized telemetry. Security is strengthened through PQC-enabled MACsec with EAP-TLS, gated shell access, SSH client strict host key check, upgraded CURL libraries, and SNMP secure-v3 configuration with SHA-2 and AES-based privacy. Operational efficiency is supported by Smart Licensing Using Policy for FCM platforms and XR version formats for service packs and special releases, delivering a comprehensive platform for scalable, secure, and simplified network operations.
For more details on the Cisco IOS XR release model and associated support, see Software Lifecycle Support Statement - IOS XR.
Table 1. New software features for ASR 9000 Series Aggregation Services Routers, Release 26.3.1
| Product impact |
Feature |
Description |
| BGP |
||
| Software reliability
|
This feature enables more complete and resilient VPN route propagation in environments with redundant external peers, while preserving existing best-path behavior and operational consistency by extending RTC (route target constraint) processing on ASBRs (autonomous systems border routers). This is achieved by installing RT membership state on all qualified eBGP multipath neighbors instead of only the best-path neighbor. |
|
| Interface and Hardware Component |
||
| Upgrade
|
Enhanced monitoring capability |
This release enhances the monitoring capability of the interfaces by enabling 128k GRE tunnels, static pseudowires, and L2 transport interfaces that operate without MAC address learning. Increasing the scale to 128k interfaces enables higher service density per chassis, reduces physical hardware requirements, optimizes operational efficiency, and supports larger, more complex network topologies without sacrificing telemetry performance. No additional configuration is required to achieve this higher scale. |
| MACsec |
||
| Software reliability
|
This feature is supported on all MACsec-supported IOS XR platforms. Introduces PQC-capable TLS key exchange support for EAP-TLS and configurable 128-bit or 256-bit EAP-derived MACsec CAK length. |
|
| Routing |
||
| Software reliability
|
This feature helps protect the network from excessive inter-area route propagation caused by misconfiguration or unexpected route growth by limiting the number of prefixes propagated between IS-IS levels. This feature, using the new maximum-propagated-prefixes command, allows operators to define propagation thresholds, receive early warnings, and optionally stop advertising additional prefixes when limits are exceeded. |
|
| Setup and Upgrade |
||
| Upgrade
|
This enhancement introduces support for new XR release version formats for service pack (SP) and special release (SR) in the install infrastructure so that XR software can correctly recognize, compare, display, and validate SP and SR versions. |
|
| System Management |
||
| Ease of use
|
Provides controls to suppress the device hostname and smart agent version in smart licensing usage reports. |
|
| Software stability
|
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. |
|
| System Monitoring |
||
| Software reliability
|
This feature preserves the contents of the IOS XR logging buffer across node reloads, router reloads, and RP failovers. Syslog messages are written to both the in-memory logging buffer and a persistent file on local storage. After a reload or failover, the system restores the logging buffer from persistent storage so that retained log messages before the event and current logs, are displayed. |
|
| System Security |
||
| Software reliability
|
You gain enhanced security and improved reliability through an upgraded embedded libcurl library. This transparent update preserves existing functionality and continues to support HTTP/1.0 and HTTP/1.1. |
|
| Software reliability
|
Gated shell access requires consent token authorization for direct root shell access initiated through supported shell commands. You gain secure, auditable control over root shell access by requiring cryptographic Consent Token authorization before granting access. This feature persists your security settings across reloads and high-availability events, helping prevent unauthorized or accidental changes while retaining familiar shell workflows after authorization. |
|
| Software reliability
|
You enhance SSH security by enforcing strict host key checking, allowing you to control how the SSH client handles new or changed server keys - accept, reject, or prompt for approval. Trusted host keys are stored system-wide and persist across reloads, ensuring consistent validation for your outbound SSH connections. |
|
| Telemetry |
||
| Software reliability
|
gNMI Internal Path sharing |
You can now reduce redundant processing and ensure that collectors receive synchronized, reliable data. With Internal Path sharing, the router automatically detects duplicate Internal Paths across different gNMI subscription lists and consolidates data collection for those paths. This optimization provides consistent data snapshots to collectors without requiring any user configuration. This feature introduces these changes: CLI:
● show telemetry subscriptions [id
● show telemetry destination endpoints [id
● show telemetry collections [id

Deprecation and phasing out features with insecure capabilities and its secure alternatives
In Release 26.3.1, Cisco IOS XR software displays warning messages when you configure features or protocols that lack sufficient security, such as those that transmit sensitive data without encryption or use outdated encryption mechanisms. The software also shows warnings when you do not follow security best practices, and it provides suggestions for secure alternatives.
This list may change, but Cisco plans to generate warnings for the following features and protocols from Release 25.3.1. Each Release Notes will describe the exact changes for that version. These documents list all features planned for removal, including insecure commands, and provide recommended secure alternatives to help you maintain network security and compliance.

Feature removal and suggested alternatives
Table 2. Deprecation and phasing out features with insecure capabilities and its secure alternatives
| If you are using the following insecure features… |
Then follow these secure alternatives… |
| TLS 1.0 TLS 1.1 |
Use TLS 1.2 or TLS 1.3. |
| SSH key-exchange algorithm diffie-hellman-group1-sha1 |
Use stronger SSH key-exchange algorithms. Do not configure diffie-hellman-group1-sha1. |
| SSH ciphers 3des-cbc |
Use stronger SSH ciphers. |
| SSH host-key DSA algorithm |
Use ECDSA, ED25519, or RSA host keys. Note: The SSH host-key DSA algorithm is not recommended. However, it has not been removed. If required, you can still generate and use DSA host keys. Cisco recommends using ECDSA, ED25519, or RSA host keys. |
| SSHv1 |
Use SSHv2. |
This section provides a brief description of the behavior changes introduced in this release.
● Deprecation of PCE NETCONF CLI
Starting with Cisco IOS XR Release 26.3.1, the PCE NETCONF CLI configuration is deprecated. Previously, you could configure NETCONF attributes directly for the Path Computation Element by using the pce netconf CLI commands. Because there is no actual operational use case for this configuration, it has been removed entirely. You do not need to perform any configuration migration or apply replacement commands, as there is no impact from this deprecation.
● Boolean values in gNMI path keys
Starting with Cisco IOS XR Release 26.3.1, Boolean list keys in gNMI Subscribe responses that use proto or JSON_IETF encoding are represented by the canonical strings true and false instead of 1 and 0. If your collector explicitly expects or compares the earlier numeric strings, update its parsing logic. You do not need to make any router configuration changes.
● Enable automatic Docker Daemon startup with Application Manager
The appmgr docker start command enables the Docker Daemon to start automatically when Application Manager starts.
Router(config)# appmgr docker start
Router(config)# commit
● Increased CPU and memory limits for TPAs
Starting with Cisco IOS XR Release 26.3.1, the maximum configurable hard resource limits for Third-Party Applications (TPAs) are increased to 100 percent of total system CPU and 80 percent of overall system memory. These limits prevent TPAs from exceeding the CPU and memory thresholds, regardless of resource usage by other IOS XR processes.
● VRF Naming Restriction
Starting with Cisco IOS-XR Release 26.3.1, the uppercase name "DEFAULT" is reserved for the OpenConfig default network instance. You must choose a different name for any user-defined VRF. This restriction applies to global VRF configuration, interface VRF assignments, and dynamic-template VRF configurations across both CLI and YANG management interfaces. Before upgrading, you must rename or remove any user-defined VRF named "DEFAULT" to prevent startup configuration validation failures. Note that VRF names are case-sensitive; variations such as "Default" or "DEFAULT1" remain valid, and the system default VRF is not affected.
● Standards-compliant OpenConfig BGP identity values
Starting with Cisco IOS XR Release 26.3.1, selected OpenConfig BGP operational values use the module-qualified identity format, such as openconfig-bgp-types:<identity>, instead of <identity>. This format clearly identifies the YANG module defining each identity. These values include notification error codes and subcodes, remove-private-AS state, and supported capabilities. Clients and automation should process the module-qualified format.
● Default values restored after delete operations
Starting with Cisco IOS XR Release 26.3.1, deleting a leaf in a native YANG configuration container restores its defined default value, ensuring consistent configuration data in show running-config and NETCONF get-config output.
● Deprecation of the show install packages command family
Starting with Cisco IOS XR Release 26.3.1, the "show install packages..." family of commands such as the commands to show install packages information, show install packages search, and show install packages are marked as deprecated. For package names and repository information for uninstalled packages, use the show install active, show install committed, and show install available commands.
● Recommended workflows for removing or deactivating bug fixes
The show install fixes deactivate command is no longer the recommended workflow for removing or deactivating a bug fix. Select one of the following workflows based on the software images and rollback points available in your environment:
o Use install rollback when a previous rollback point exists where the same Cisco IOS XR version was loaded without the bug fix.
o Use show install rollback ? to identify a suitable rollback point.
o Use install replace when a suitable previous golden ISO image is available without the bug fix.
o If no previous rollback point or suitable golden ISO image exists, build a new golden ISO image with the desired set of fixes.
o If the golden ISO build fails or still includes the unwanted bug fix, the desired set of fixes cannot be built with the available fixes. Contact Cisco Support for a new version of the unwanted fix.
● Provider Backbone Bridging Removed
Starting from Cisco IOS XR Release 26.3.1, Provider Backbone Bridging (PBB), including IEEE 802.1ah PBB, PBB-VPLS, and PBB-EVPN related configuration and operational commands, is removed. PBB has been deprecated since Cisco IOS XR Release 7.11.1. PBB configuration is no longer available in the configuration interface. In earlier releases, PBB configuration, if present, has no operational effect.
● ZTP provisioning in nV Satellite mode
When the device is in nV Satellite mode, ZTP does not bring interfaces up or down and does not attempt to download or apply configuration. This preserves host-controlled satellite operation.
There are no open issues in this release.
There are no known issues in this release.
