Intermediate System to Intermediate
System (IS-IS)
The intermediate system to intermediate system (IS-IS) protocol for IPv4 and IPv6 is supported on the
S4810 platform.
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 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.
