Intermediate System to Intermediate

System (IS-IS)

The intermediate system to intermediate system (IS-IS) protocol for IPv4 and IPv6 is supported on the

S6000platform.

IS-IS is an interior gateway protocol that uses a shortest-path-first algorithm. IS-IS facilitates the

communication between open systems, supporting routers passing both IP and OSI traffic.

A router is considered an intermediate system. Networks are partitioned into manageable routing

domains, called areas. Intermediate systems send, receive, and forward packets to other routers within

their area (Level 1 and Level 1-2 devices). Only Level 1-2 and Level 2 devices communicate with other

IS-IS protocol standards are listed in the Standard Compliance chapter in the Dell Networking OS

Configuration Guide.

NOTE: The fundamental mechanisms of IS-IS are the same between IPv4 and IPv6. Where there are

differences between the two versions, they are identified and clarified in this chapter. Except where

identified, the information in this chapter applies to both protocol versions.

adjacency-check

Verify that the "protocols supported" field of the IS-IS neighbor contains matching values to this router.

adjacency-check

To disable adjacency check, use the no adjacency-check command.

This guide is platform-specific. For command information about other platforms,
