    摘要: In one embodiment, a plurality of leaf switches that include host facing ports are configured as a cloud switch. An indication of connectivity between the leaf switches of the cloud switch and routing bridges (RBridges) external to the cloud switch may be added to link state packets (LSPs) sent over the at least one logical shared media link. A lookup table may be generated that specifies next hop leaf switches. The generated lookup table may be used to forward frames to one or more particular nexthop leaf switches. Further, traffic engineering parameters may be collected. Equal cost multipath (ECMP) nexthop leaf switches and distribution trees to reach one or more destinations may be examined. Traffic may be distributed across ones of them based on the traffic engineering parameters.

    摘要: In one embodiment, one or more indicia of stress are monitored. Based on the one or more indicia of stress, it is determined a stress condition exists. In response to the stress condition, one or more link aggregation actors and partners are caused to enter a grace state for a grace period. While the one or more link aggregation actors and partners are in the grace state, link aggregation formation is paced on a plurality of links by delaying formation of one or more new link aggregation groups on the plurality of links until a hold is released. Upon expiration of the grace period, the grace state is exited.

    摘要: In one embodiment, a first number of multiple spanning tree instances (MSTIs) are defined within a network. A second number of network segments associated with segmentation identifier (IDs) are also configured, where the first number of MSTIs is less than the second number of segmentation IDs. Segmentation ID to MSTI mappings are maintained that map each defined segmentation ID of the second number of network segments to one of the first number of MSTIs. A segmentation mapping digest is computed of the segmentation ID to MSTI mappings. Multiple spanning tree (MST) bridge protocol data units (BPDUs) are broadcast that include the digest of the segmentation ID to MSTI mappings.
