IPv4 NLRI with IPv6 Next Hop (RFC 5549)

IP Fabric currently does not support routing tables that follow RFC 5549, where IPv4 routes are advertised with an IPv6 next hop using MP-BGP.

The current routing model in IP Fabric assumes that:

  • IPv4 routes use an IPv4 next hop
  • IPv6 routes use an IPv6 next hop

As a result, routing information that relies on RFC 5549 is not correctly represented and may be missing or incomplete in routing tables, path lookup, and reachability analysis.
