Guidelines and Limitations

Enabling an Address-Family

In IOS-XR, simply enabling an address-family under IS-IS (e.g., address-family ipv4 unicast) is a valid and meaningful configuration, even without any additional sub-attributes. There are two supported ways to enable an address-family:

address_family:
  # 1. Enabled by having attributes configured in the address-family
  ipv4_unicast:
    distance: 100
    maximum_paths: 10

  # 2. Explicitly enabled
  ipv6_unicast:
    enable: true

Note: Both forms produce the same result on the device. Declaring a key with no value (e.g., ipv6_unicast:) is not valid; use enable: true instead.

ISIS Interface Examples

IS-IS interfaces allow per-interface control of adjacency formation, authentication, timers, BFD, mesh groups, circuit types, priorities, and LSP transmission parameters. This resource supports passive interfaces, point-to-point links, level-specific configurations, MPLS LDP synchronization, and advanced features like delay normalization and affinity-based traffic engineering.

ISIS Interface Address Family Examples

This resource manages per-interface, per-address-family configuration including metrics, segment routing prefix SIDs, fast-reroute (FRR) protection with TI-LFA and remote LFA, adjacency SIDs, link groups, and prefix advertisement policies. Supports both IPv4 and IPv6 address families with unicast and multicast sub-address families.
