Routing Protocols

This chapter describes the IP unicast routing protocols available on the
BlackDiamond. 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

The BlackDiamond supports the use of the Routing Information Protocol (RIP) and 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.
