1. A method comprising:
- receiving a link state advertisement, wherein the link state advertisement is received at a first node of a communication system, and the link state advertisement comprises a hop count field;
incrementing the hop count field; and
transmitting the link state advertisement in response to a determination that the hop count field is less than a maximum hop count value and a determination that an instance of the link state advertisement has not been generated during a minimum link state advertisement interval.

Abstract
A method of operating an network is described. The network includes a number of nodes connected by a number of links. A method according to the present invention provisions a virtual path between a first and a second one of the plurality of nodes by: identifying the first and the second nodes, discovering a physical path from the first node to the second node, and establishing the virtual path. The method discovers a physical path from the first node to the second node by automatically identifying nodes forming the physical path. The method establishes the virtual path by configuring a set of connections between the nodes forming the physical path.
