<p>It is disclosed a method for exchanging information for establishing a path between a first node and a second node of a communication network. The first node and the second node are operable to send continuity check messages for monitoring the established path. The method comprises: generating, at the first node and at the second node, at least one link state message according to a routing protocol; inserting continuity check link state information into the at least one link state message; and exchanging, between the first node and the second node, the link state messages for computing the path. The continuity check link state information are indicative of at least one rate of transmission of the continuity check messages supported by the first node and the second node.</p> |
