  • Collapsed forwarding for service domain routers
    Patent number: 10069725
    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.
