Configuring RIP

This chapter describes how to configure Routing Information Protocol (RIP)
on the switch. RIP is a dynamic routing protocol for IPv4 networks.
The topics covered in this chapter include:

RIP Overview
RIP is an Interior Gateway Protocol (IGP) that performs dynamic routing
within a network. PowerConnect 8000-series and 8100-series switches support
two dynamic routing protocols: OSPF and Routing Information Protocol
(RIP).
Unlike OSPF, RIP is a distance-vector protocol and uses UDP broadcasts to
maintain topology information and hop counts to determine the best route to
transmit IP traffic. RIP is best suited for small, homogenous networks.

How Does RIP Determine Route Information?

The routing information is propagated in RIP update packets that are sent
out both periodically and in the event of a network topology change. On
receipt of a RIP update, depending on whether the specified route exists or
does not exist in the route table, the router may modify, delete or add the
route to its route table.
RIP uses hop count, which is the number of routers an IP packet must pass
through, to calculate the best route for a packet. A route with a low hop count
is preferred over a route with a higher hop count. A directly-connected route
