Hi guys,
frr has ipv6 support for isis. I think it is useful to add that to replace ospfv2/v3 completely.
https://docs.frrouting.org/en/latest/isisd.html
interface eth1 ipv6 router isis VyOS ip router isis VyOS
Vyos only adds ipv4 adjacency not ipv6.
Please bump up frr version and add IPv6 support for isis. I will be extremely useful.
Thanks.
