This feature adds support for user-configured BGP Nexthop Resolution RIB profiles for various BGP-based services e.g. IP unicast, L3 VPN, EVPN, etc. The feature allows an administrator to customize the next hop resolution semantics of BGP routes with an ordered list, or profile, of resolution RIB domains (i.e., either tunnel or IP domain). This allows EOS to direct specific services over the specified RIB domains, overriding the default behavior.

This feature provides support for advertising IPv4 unicast Network Layer Reachability Information (NLRI) with

BGP RFC5549 4.22.1F Next Hop

This feature provides support for advertising VPN-IPv4 Network Layer Reachability Information (NLRI) with IPv6 next-hops over IPv6 peering sessions described as the Extended Next Hop Encoding capability in RFC8950. Extended Next Hop Encoding capability can be supported for IPv4 unicast, IPv4 Labeled Unicast, and IPv4 VPN address and sub-address families (1/1, 1/4, 1/128 respectively) per RFC. The Extended Next Hop support for IPv4 unicast is described in RFC 5549 .
