BGP IPv6 LU over non-colored IPv6 SR-TE Tunnel with IPv6 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 IPv6 prefixes with an IPv6 next-hop address. In this case, BGP-LU can resolve IPv6 routes over non-colored SR-TE tunnels established in a network with the IS-IS protocol distributing IPv6 segment routing SIDs.
