Software Features Introduced in Cisco IOS XR Software Release 6.3.2

IS-IS VRF Aware Lite

The feature adds the possibility to run an Integrated Intermediate System-to-Intermediate System (IS-IS) process in the context of a non-default VPN routing and forwarding (VRF). Both IPv4 and IPv6 are supported. The implementation is more suitable for VRF-lite scenarios.

For more information, see the Routing Configuration Guide for Cisco NCS 5000 Series Routers, IOS XR Release 6.3.x.

LLDP Model Local System Information

The LLDP model local system information feature provides Open-Config (OC) Model support for LLDP. With this model, you can perform the create, modify, delete operations by using the YANG model through RPC request. For more information, see the Using Data Models chapter in Programmability Configuration Guide for Cisco NCS 5000 Series Routers.

RPM Signing and Verification

Cisco IOS XR supports RPM signing and signature verification for Cisco IOS XR RPM packages in the ISO and upgrade images. All RPM packages in the Cisco IOS XR ISO and upgrade images are signed to ensure cryptographic integrity and authenticity. This guarantees that the RPM packages have not been tampered with and the RPM packages are from Cisco IOS XR. The private key, used for signing the RPM packages, is created and securely maintained by Cisco.

IP-MIB Support for IPv4

IOS-XR implementation of IP-MIB now supports IPv4 statistics as per RFC4293. Refer to the SNMP OID Navigator for a list of new OIDs added for iPv4 statistics.

LLDP YANG Models

Link Layer Discovery Protocol (LLDP) YANG model supports configuring event-driven telemetry.

For an example about configuring event-driven telemetry for LLDP, see Configure Model-driven Telemetry chapter in Telemetry Configuration Guide for Cisco NCS 5000 Series Routers.

NETCONF Transport for Event-Driven Telemetry

Support for NETCONF as a transport for event-driven telemetry.

For information about NETCONF notifications, see Configure Model-driven Telemetry chapter in Telemetry Configuration Guide for Cisco NCS 5000 Series Routers.

Enhancements to Programmability

Cisco IOS XR supports Network-Instance, LLDP, and ISIS Open Config Models. These models have YANG models defined for configuration and operational data.

For more information about YANG data models and configuration, see Using Data Models chapter in Programmability Configuration Guide for Cisco NCS 5000 Series Routers.

Increase in Throttle Memory Range

The high range of memory usage per session by the XML agent is increased from 600 MB to 1024 MB. Supported only on IOS XR 64-bit OS.

For more Information about configuring the XML agent, see Configuring Manageability chapter in System Management Configuration Guide for Cisco NCS 5000 Series Routers .

Behavior Change Introduced in Cisco IOS XR Release 6.3.2

From this release onwards address-family is a mandatory keyword for the show tech-support multicast command. The command syntax is:

show tech multicast address-family <ipv4/ipv6>.

For more information, refer the show tech-support multicast command in the Tech-Support Commands chapter of the Advance System Command Reference for Cisco NCS 5000 Series Routers.

Production Software Maintenance Updates (SMUs)

A production SMU is a SMU that is formally requested, developed, tested, and released. Production SMUs are intended for use in a live network environment and are formally supported by the Cisco TAC and the relevant development teams. Software bugs identified through software recommendations or Bug Search Tools are not a basis for production SMU requests.

For information on production SMU types, refer the Production SMU Types section of the IOS XR Software Maintenance Updates (SMUs) guide.
