[FROG] BGP VPN-VRF route leaking per RFC 4364

All - I'd like to thank Paul Ziemba, Lou Berger and Renato Westphal for their work on getting FRR to allow BGP VPN-VRF route leaking. This is per RFC 4364. The new syntax for this is: router bgp <as> [vrf <FOO>] address-family <afi> unicast rd (vpn|evpn) export (AS:NN | IP:nn) label (vpn|evpn) export (0..1048575) rt (vpn|evpn) (import|export|both) RTLIST... nexthop vpn (import|export) (A.B.C.D | X:X::X:X) route-map (vpn|evpn|vrf NAME) (import|export) MAP [no] import|export [vpn|evpn|evpn8] [no] import|export vrf NAME Further documentation can be found in doc/user/bgp.rst thanks! donald
