Abstract: In one embodiment, a service domain router (SDR) establishes a virtual fabric interface between the SDR and at least one peer SDR in a computer network. When the SDR receives a routing advertisement from the peer SDR, where the routing advertisement provides nexthop (NH) information for one or more network routes, the SDR may add the one or more network routes to a routing information base (RIB) listing the peer SDR as a next-to-nexthop (NNH) for the network routes. A forwarding information base (FIB) on the network device then resolves the NNH for the corresponding network routes to an egress interface of the peer SDR, such that packets received at the SDR and destined along a particular route of the one or more network routes may be forwarded via the egress interface of the peer SDR.

Abstract: Presented herein are techniques that remove the unnecessary provisioning system complexities of manual inter-domain service/circuit stitching by introducing a solution to perform dynamic end-to-end circuit setup in a hybrid networking environment. A method is provided that is performed by a gateway node at a boundary of a first domain and a second domain of a hybrid network, the first domain and the second domain using different types of transport and different types of control planes.
