Abstract
Official abstract text for this publication.
Techniques for efficiently updating routing information in a network device such as a router. According to an embodiment of the present invention, the routing information is updated upon creation or deletion of an overlay tunnel without the network device having to regenerate a Shortest Path Tree (SPT) by performing full Shortest Path First (SPF) processing.
First claim
Opening claim text (preview).
What is claimed is: 1. A system comprising: a memory configured to: store routing information used by the system for forwarding a packet from the system; and store information for a shortest path tree (SPT) generated by the system, the SPT comprising a first node and a second node; and a processor configured to: determine a first cost metric indicative of a cost for communicating data from the first node to the second node via a path from the first node to the second node…
