bgpd: Generate and advertise gateway IP overlay index with EVPN RT-5
Gateway IP overlay index is generated for EVPN RT-5 when following CLI is
configured.
router bgp 100 vrf vrf-blue
address-family l2vpn evpn
advertise ipv4 unicast gateway-ip
advertise ipv6 unicast gateway-ip
BGP nexthop of the VRF IP/IPv6 route is set as the gateway IP of the
