UCMP for LU over v4/v6

The BGP labeled-unicast (LU) RFC is used to advertise BGP routes with a stack of MPLS labels, thereby allowing distribution of MPLS tunnel paths through BGP. This feature enables deriving and using link-bandwidth attribute for BGP LU paths which further enables applying weighted nexthop sets for BGP LU routes installed in IP FIB and for IP routes resolving over LU tunnel routes. As part of UCMP support for BGP LU routes, the following functionality has been added: IP routes resolving over BGP LU routes should be able to inherit the link-bandwidth information from the resolving BGP LU route (if the...
