Description

Summary

extend the ability SRv6 which enables extensions in IS-IS to support Segment Routing over IPv6
data plane (SRv6) as per RFC 9352.

Use case

enable SRv6 on a specific IS-IS area and assign an already configured SRv6 locator to it.

example FRR:

router isis VyOS
 is-type level-2-only
 net 49.0000.0000.0000.0001.00
 segment-routing srv6
  locator NAMEXXX
 exit

Additional information

it should be a command in our cli similar to it :

set protocols isis segment-routing srv6 locator NAMEXXX
vyos eg :

set protocols isis interface eth1
set protocols isis interface lo
set protocols isis level 'level-2'
set protocols isis net '49.0000.0000.0000.0001.00'
set protocols isis segment-routing srv6 locator NAMEXXX
