Abstract

In one embodiment, a network comprises a first forwarding domain using a first data plane forwarding protocol and a second forwarding domain using a second data plane forwarding protocol different than the first data forwarding plane forwarding protocol. The first forwarding domain includes a first path node and a particular border node. The second forwarding domain includes a second path node and the particular border node. The particular border node performs Segment Routing or other protocol interworking between the different data plane forwarding domains, such as for transporting packets through a different forwarding domain or translating a packet to use a different data forwarding protocol. These forwarding domains typically include Segment Routing (SR) and SR-Multiprotocol Label Switching (SR-MPLS). Paths through the network are determined by a Path Computation Engine and/or based on route advertisements such associated with Binding Segment Identifiers (BSIDs) (e.g., labels, Internet Protocol version 6 addresses).
