BGP classful transport (CT) - Transport family

This feature introduces the BGP transport address family, used in BGP classful transport planes. Use the BGP classful transport planes feature to configure transport classes for classifying a set of transport tunnels in an intra-AS network based on the traffic engineering characteristics. The transport classes put the set of transport tunnels in separate transport RIBs and use these transport routing information bases (RIBs) to resolve service routes with the desired SLA and intended fallback. BGP classful transport planes can extend these tunnels to inter-domain networks that span multiple domains (autonomous systems or IGP areas) while preserving the transport class. To do this, you must configure the BGP classful transport layer BGP family between the border and service nodes.
