Abstract
Techniques for updating a routing table based on a single message are described. One technique includes receiving at a first network device a node message from a second network device. The node message includes a sequence number and a list of link state(s) originated by the second network device. The first network device determines whether to withdraw one or more link states originated by the second network device and maintained in a routing table of the first network device based on the sequence number and the list of the link state(s) within the node message. The routing table is updated based on the determinations.
