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 three 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

  # 3. Enabled with empty mapping
  ipv4_multicast: {}

Note: All three forms produce the same result on the device. The enable: true form is preferred for clarity. The empty mapping {} is also supported. Declaring a key with no value (e.g., ipv6_unicast:) is not valid; use enable: true or {} 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.
