Intermediate System to Intermediate System (ISIS) Routing Protocol

OSI Intermediate System (IS) to Intermediate System routing is a protocol used to exchange information between Level 1 (intra-domain) routing devices in an OSI network. The OSI Intra-Domain IS-IS Routing Protocol may be used as an interior gateway protocol (IGP) to support TCP/IP as well as OSI. This allows a single routing protocol to be used to support pure IP environments, pure OSI environments, and dual environments. A specification has been developed by the IS-IS working group of the Internet Engineering Task Force. The OSI IS-IS protocol has reached a mature state, and is ready for implementation and operational use. The most recent version of the OSI IS-IS protocol is contained in ISO DP 10589 [1]. The proposed standard for using IS-IS for support of TCP/IP will therefore make use of this version (with a minor bug correction, as discussed in Annex B). We expect that future versions of this proposed standard will upgrade to the final International Standard version of IS-IS when available.
