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 BGP table version is 2, local router ID is 10.0.0.5, vrf id 0 Default local pref 100, local AS 65000 Status codes: s suppressed, d damped, h history, * valid, > best, = multipath, i internal, r RIB-failure, S Stale, R Removed Nexthop codes: @NNN nexthop's vrf id, < announce-nh-self Origin codes: i - IGP, e - EGP, ? - incomplete Network Next Hop Metric LocPrf Weight Path Route Distinguisher: 65003:3003 *>ifc:3::/64 fe80::200:ff:fe00:0 0 100 0 i UN=fe80::200:ff:fe00:0 EC{65003:3003} label=81 type=bgp, subtype=0 *>ifc:33::/64 fe80::200:ff:fe00:0 0 100 0 65303 i UN=fe80::200:ff:fe00:0 EC{65003:3003} label=81 type=bgp, subtype=0 Route Distinguisher: 65008:8 *>ifc:8::/64 fe80::200:ff:fe00:0 0 100 0 i UN=fe80::200:ff:fe00:0 EC{65001:1001 65003:3003 65004:4004} label=82 type=bgp, subtype=0 Displayed 3 routes and 3 total paths
