  • Patent number: 8842517
    Abstract: A method is provided in one example embodiment and includes receiving a first pseudo-node identifier associated with a first network node via a network. The first pseudo-node identifier is generated by the first network node in a first designated intermediate system (DIS) operation. The method further includes detecting a loss of connectivity to the first network node, and receiving a second pseudo-node identifier associated with a second network node via the network. The second pseudo-node identifier is generated by the second network node in a second DIS operation. The method further includes executing a first network path determination operation using the first pseudo-node identifier and the second pseudo-node identifier when an elapsed time between the detecting of the loss of connectivity with the first network node and the executing of the first network path determination operation is within a predetermined threshold.

  • Patent number: 8792384
    Abstract: A method is provided in one example embodiment and includes establishing a communication pathway between a first network node and a second network node coupled to a network; forming an adjacency to a new network node coupled to the network, where a designated intermediate system (DIS) election operation is executed after the adjacency is formed in order to determine that the new network node is a newly identified DIS for the network; and communicating a message advertising connectivity to both a previously identified DIS and the newly identified DIS, where the message is communicated during a specified time interval.
