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 allows transport of multicast frames to an endpoint across an IP network by tunneling them through MPLSoGRE or MPLSoGUE. The tunneling of multicast frames is achieved with a traffic policy applied on the ingress interface which will match on all packets destined to a multicast IP address and redirect that traffic to a MoG nexthop group. The traffic policy will also specify “forced routing” in order to set the fwd_layer_index to 1 so that the L2 header is removed before encapsulation.
