BGP IPv4 LU over static Colored SR-TE Tunnel with IPv4 IS-IS

This feature extends the support for the BGP Labeled Unicast (BGP-LU) service for color-based mapping of VPN services over segment routing-traffic engineering (SR-TE) LSPs. Specifically, this feature enables you to advertise BGP-LU IPv4 prefixes with an IPv4 next-hop address. In this case, BGP-LU can resolve IPv4 routes over static colored SR-TE tunnels established in a network with the IS-IS protocol distributing IPv4 segment routing SIDs. BGP-LU constructs a colored protocol next hop, which is resolved on a colored SR-TE tunnel.
