Chapter 21 OSPF<br />

Open Shortest Path First (OSPF) is supported by <strong>FTOS</strong> on all <strong>Force10</strong> plat<strong>for</strong>ms (C-<strong>Series</strong>,<br />

OSPF is an Interior Gateway Protocol (IGP), which means that it distributes routing<br />

in<strong>for</strong>mation between routers in a single Autonomous System (AS). OSPF is also a link-state<br />

protocol in which all routers contain <strong>for</strong>warding tables derived from in<strong>for</strong>mation about <strong>the</strong>ir<br />

links to <strong>the</strong>ir neighbors.<br />

The <strong>Force10</strong> <strong>Networks</strong> implementation of OSPF is based on IETF RFC 2328. The following<br />
