One can not <TAB> complete the BGP peer-groups when working inside the VRF tree
To reproduce:
set vrf name red protocols bgp neighbor 100.64.151.254 peer-group 'PG-VYOS-123' set vrf name red protocols bgp peer-group PG-VYOS-123 address-family ipv4-unicast nexthop-self set vrf name red protocols bgp peer-group PG-VYOS-123 bfd set vrf name red protocols bgp peer-group PG-VYOS-123 capability dynamic set vrf name red protocols bgp peer-group PG-VYOS-123 remote-as 'internal' set vrf name red protocols bgp system-as '2000' set vrf name red table '2000'
set vrf name red protocols bgp neighbor 100.64.151.222 peer-group <TAB> does not list PG-VYOS-123 as possible completion
