10Routing Protocols

This chapter describes the IP unicast routing protocols available on the Summit. It assumes that you are already familiar with IP unicast routing. If not, refer to the following publications for additional information:

RFC 1058 — Routing Information Protocol (RIP)

RFC 1256 — ICMP Router Discovery Messages

RFC 1723 — RIP Version 2

RFC 2178 — OSPF Version 2

OVERVIEW

The Summit switch supports the use of either the Routing Information Protocol (RIP) or the Open Shortest Path First (OSPF) protocol for IP unicast routing.

RIP is a distance vector protocol, based on the Bellman-Ford (or distance vector) algorithm. The distance vector algorithm has been in use for many years, and is widely deployed and understood.

OSPF is a link state protocol, based on the Dijkstra link state algorithm. OSPF is a newer Interior Gateway Protocol (IGP), and solved a number of problems associated with using RIP on today’s complex networks.
