Abstract:
1. For use with a node of a communication network, a method comprising: a) accepting, using the node, status information indicating a state of each of at least two different kinds of routing protocols; b) composing, using the node, an aggregated message including at least two indicators, each indicator identifying a different one of the at least two different kinds of routing protocols and the corresponding status information indicating a state of each of the at least two different kinds of routing protocols as data within the aggregated message; c) sending, using the node, the aggregated message towards a neighbor node; d) maintaining, using the node, a first timer tracking a send time interval, wherein the acts of composing the aggregated message and sending the aggregated message are performed after each recurring expiration of the first timer; and e) restarting, using the node, the first timer after the aggregated message is sent, wherein the aggregated message further includes a single dead time interval associated with all of the at least two different kinds of routing protocols, wherein the send time interval is less than the single dead time interval, and wherein the single dead time interval defines a time interval after which, if no further aggregated message is received, all of the at least two different kinds of routing protocols are declared as down.
