Abstract
In one embodiment, a method includes receiving a first link state initiation (HELLO) message from a first neighboring router. The HELLO message requests that a recipient node send a unique identifier for itself in a link state routing protocol. In response to receiving the first HELLO message, a first response message is sent that includes a first identifier from an identifier pool. The identifier pool contains for a local node a plurality of network identifiers that are unique among all nodes in the network that uses the link state routing protocol. A second HELLO message is received from a different second neighboring router. In response to receiving the second HELLO message, a second response message is sent that includes a different second identifier from the identifier pool.
