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.
Claims20
A method, comprising:
- 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, wherein 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 via both a previously identified DIS and the newly identified DIS, wherein the message is communicated during a specified time interval.
Logic encoded in non-transitory media that includes code for execution and when executed by a processor operable to perform operations comprising:
- 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, wherein 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 via both a previously identified DIS and the newly identified DIS, wherein the message is communicated during a specified time interval.
An apparatus, comprising:
- a memory element configured to store electronic code;
- a processor operable to execute instructions associated with the electronic code;
- and
- a connectivity module configured to interface with the processor such that the apparatus is configured for:
- 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, wherein 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 via both a previously identified DIS and the newly identified DIS, wherein the message is communicated during a specified time interval.
