Abstract: Disclosed are systems and methods for scaling Massively Scalable Data Center (MSDC) networks with a large number of end-point tunnels utilizing Equal-cost multi-path routing (ECMP). The systems and methods can use the NO-OP label operations to maintain single ECMP objects to switch a set of segment routing tunnels that share the same ECMP links. The forwarding engine can determine the use of the NO-OP label operation and update a received packet to enable the use of the single ECMP objects of the set of segment routing tunnels.

Abstract: Techniques are provided for optimizing multicast routing in a network. At a router device, a message is sent to one or more physical devices. The message is configured to solicit a response indicating a network assignment for each of the physical devices. A response message is received from each of the physical devices. The response message comprises network assignment information for each of the physical devices. For each of the physical devices, the network assignment information is translated into a segment identifier. The segment identifier is distributed to other router devices in the network.

Abstract: A method is provided in one example and includes broadcasting a switching node identifier associated with a first link-state protocol enabled switching node to a plurality of link-state protocol enabled switching nodes. The plurality of link-state protocol enabled switching nodes are in communication with one another by a link-state protocol cloud. The method further includes broadcasting a priority associated with the first link-state protocol enabled switching node to the plurality of link-state protocol enabled switching nodes. The method further includes broadcasting connectivity information of the first link-state protocol enabled switching node to the plurality of link-state protocol enabled switching nodes using the link-state protocol cloud. The connectivity information includes connectivity of the first link-state protocol enabled switching node with at least one spanning tree protocol enabled switching node.
