Job -
We were unaware of RFC 7606 and I've opened an issue to get this
implemented: https://github.com/FRRouting/frr/issues/3583
Thanks for pointing this out to us.
Ah, nice! I’m confident many FRR users will benefit from 7606 style handling. This will be a good improvement for the routing stack.
Another RFC you may want to consider: RFC 8212. :-)
Kind regards,
Job
