Hi, <<Reposting this question again, there was conversation happened regarding this 2=3 years back, but i still see the change log showing support for RFC 4552 https://lists.frrouting.org/pipermail/dev/2017-September/000899.html

...

Does FRR 3.0 support OSPFv3 authentication? Though OSPFv3 doesn't have an authentication header on its own similar to OSPFv2, it should use IPSec for authentication. Though github claims that it supports RFC 4552. Reference Link:https://github.com/FRRouting/frr/wiki/FRR-2.0-%E2%86%92-FRR-3.0-Changelog But I couldn't see commands like "ipv6 ospf authentication .." etc., Do I miss something?Regards, Jagadeesh N
