  • BGP Classful Transport planes (BGP-CT) to facilitate service mapping over colored tunnels (ACX Series, PTX Series, MX Series)—Starting in Junos OS Release 21.1R1, you can classify colored transport tunnels (RSVP, IS-IS flexible algorithm) in your network into transport classes and map service routes over an intended transport class. You can also extend the transport tunnels to span across multiple domains (ASs or IGP areas) by using the new BGP transport address family called BGP Classful Transport (BGP CT).

    This feature lays the foundation for network slicing and allows the different domains to interoperate irrespective of the transport signaling protocols used in each domain.
