Abstract:
1. A network component, comprising: a non-transitory storage medium; an interface associated with a neighboring network component; and a first processor coupled with the non-transitory storage medium and the interface, wherein the first processor has instructions to determine whether the neighboring network component is reachable and instructions to generate a neighbor database summary list for forming a full adjacency between the network component and the neighboring network component, wherein the instructions to the first processor are configured to: compute a time period between a time when the network component starts to generate a neighbor database summary list and a time when the neighboring network component becomes unreachable; and generate the neighbor database summary list, wherein: the neighbor database summary list is empty if the neighboring network component is reachable; the neighbor database summary list comprises a header of every Link State Advertisement (LSA) whose content changed in a link state database of the network component after the neighboring network component becomes unreachable if the neighboring network component is unreachable, a time period between a time when the network component starts to generate the neighbor database summary list and a time when the neighboring network component becomes unreachable is less than a LSA maximum age, and the neighboring network component is not restarted after becoming unreachable; the neighbor data summary list comprises an entire link state database if the neighboring network component is restarted after becoming unreachable and a time period between a time when the network component starts to generate the neighbor database summary list and a time when the neighboring network component becomes unreachable is not less than a LSA maximum age.
