Claim Text:
1. A partially-participating link state protocol node, comprising: storage storing a local link state database; one or two interfaces sending and receiving link state protocol packets; and one or more processing elements and memory; wherein the partially-participating link state protocol node maintains the local link state database that is a portion of a network link state database of the network related to the partially-participating link state protocol node, but not the entire network as maintained by a network node operating a full implementation of a link state protocol, which includes the partially-participating link state protocol node only updating the local link state database based on link state protocol data units (LSPs) received in a link state protocol packets on an interface of said one or two interfaces in response to determining that said LSPs were originated by the partially-participating link state protocol node.
