Intermediate System to Intermediate System (IS-
IS)
The intermediate system to intermediate system (IS-IS) protocol for IPv4 and IPv6 is supported on the E-Series and
S4810 platforms.
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 areas.
IS-IS protocol standards are listed in the Standard Compliance chapter in the
FTOS 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.
