Patent ID: 7609672

Claim:
A method for sharing routing information on a network with mobile routers, comprising the steps of: receiving at a local router all routing information at a certain level of detail for all routers communicating in a current flooding domain, determining a measure of scale of a flooding domain that includes the current flooding domain; determining whether the measure of scale exceeds a threshold; and if it is determined that the measure of scale exceeds the threshold, then performing the steps of: sending, over a particular link of the plurality of links, a router announcement message that indicates the local router is a flooding domain border router (FDBR); determining first summary routing information with less than the certain level of detail for a first plurality of routers connected to the local router through a set of one or more links of the local router different from the particular link; and sending the first summary routing information over the particular link in a link state message that includes type data that indicates summary routing information that crosses a FDBR.
