Feature configuration

This user configures the 32-bit LSR-ID on a LDP peer or targeted peer using the following CLI:

config>router>ldp>interface-parameters>interface>ipv6>local-lsr-id interface [32bit-format]

config>router>ldp>interface-parameters>interface>ipv6>local-lsr-id interface-name interface-name [32bit-format]

config>router>ldp>targeted-session>peer>local-lsr-id interface-name [32bit-format]

When the local-lsr-id command is enabled with the 32bit-format option, an SR OS LSR is able to establish a LDP IPv6 Hello adjacency and a LDP IPv6 session with a RFC 7552 compliant peer or targeted peer LSR using a 32-bit LSR-ID set to the value of the IPv4 address of the specified local LSR-ID interface and a 128-bit transport address set to the value of the IPv6 address of the specified local LSR-ID interface.

Note: The system interface cannot be used as a local LSR-ID with the 32bit-format option enabled as it is the default LSR-ID and transport address for all LDP sessions to peers and targeted peers on this LSR. This configuration is blocked in CLI.

If the user enables the 32bit-format option in the IPv6 context of a running LDP interface or in the targeted session peer context of a running IPv6 peer, the already established LDP IPv6 Hello adjacency and LDP IPv6 session is brought down and re-established with the new 32-bit LSR-ID value.

The detailed control plane procedures are provided in LDP LSR IPv6 operation with 32-bit LSR-ID.
