IS-IS is an IGP specified and standarized by ISO and incorporating extensions to support IP. It has been deployed successfully in the Internet for several years years. The IS-IS Working Group is chartered to document current protocol implementation practices and improvements, as well as to propose further extensions to be used within the scope of IS-IS and IP routing. Short term, the WG is expected to deliver a set of documents describing common implementation practices and extensions necessary to scale the protocol. These specifications will encourage multiple, inter-operable vendor implementations. This working group will interact with other standards bodies that have responsibility for standardizing IS-IS. The status of the WG documents maintained by the WG chairs can be found at http://skat.usc.edu/~tli/Schedule.htm.
