There is one useful command missing on VyOS 1.4 (Tested VyOS 1.4-rolling-202110180513):
sh bgp ipv6 vpn
The command should output all VPNv4/VPNv6 BGP routes
Very useful for MPLS L3VPN troubleshooting
There is no command in VyOS:
vyos@VyOS-RR:~$ sh bgp ipv6 vpn Incomplete command: show bgp ipv6 vpn
But there is a command in FRR:
sh bgp ipv6 vpn
