Hi All,
BGP connection between 2 Nodes with IPv6 on global IPs and want to route via global ipv6 address not via ipv6 link local address
I have made the bgp connection with global ipv6 address of interface and advertising the ipv6 route when advertising the route then bgp route added on Node2 for 2003:4001:5001::/64 via fe80::6548:ed45:d5d:b578:link address of Node1 but i want route with via 5001:1::9 global ipv6 address (2003:4001:5001::/64 via 5001:1::9)
Similarly when we advertise 8001:1::/64 from Node2, So want help so that I can achieve the bgp route added on Node1 and Node2 via global ipv6 address not with ipv6 link address
