A hub router of the hub-and-spoke network including a memory and a processor may perform the techniques. The memory may be configured to store a representation of a topology of the hub-and-spoke network. The processor may be configured to utilize a separate instance of a multi-instance version of a link state protocol to communicate with each of a plurality of spoke routers of the hub-and-spoke network. Each separate instance of the multi-instance version of the link state protocol may include the hub router and a different one of the plurality of spoke routers. The processor may process link state advertisements from the separate instances of the multi-instance version of the link state protocol to maintain the representation of the topology of the hub-and-spoke network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Managing routing information in a hub-and-spokes network","description":"In general, techniques are described for managing routing information in a hub-and-spoke network in a manner that reduces flooding of link information.
