@Viacheslav it must be added in the proper order and contexts need to be entered - exited appropriately
It is implemented in VyOS 1.4
Problem is because of LSP MTU missmatch
I have boiled down your commands to the following:
Can't reproduce on VyOS 1.3.0-rc4, even after a reboot I get a single ipv6 route ::/0 2a01:9820:5::10 table 100 line
I see no connected network in your FIB for 2001:19f0:ffff::1 I guess that's the reason.
This requires a fix to https://github.com/FRRouting/frr/issues/8403 first
Fixed in
Retested this with VyOS 1.3.0-rc3 and the bahavior is the same.
