Abstract:
1. An apparatus for communicating packets in a network environment, comprising: a first network element operable to communicate with a second network element in order to achieve adjacency, wherein the adjacency is achieved by the first network element communicating a first summary update to the second network element and by the second network element communicating a second summary update to the first network element, and wherein the first and second summary updates include, at least, locally generated state information and a single link state, the first and second network elements each including a link state database operable to store the first and secondary summary updates in the first and second network elements respectively, the first network element using out of band resynchronization after the adjacency is achieved in order to achieve full synchronization of the link state databases, the single link state describing reachable destinations in an associated network, whereby each of the reachable destinations includes a destination and a cost metric.
