RIP

This chapter shows you how to configure RIP (Routing Information Protocol).

36.1 RIP Overview

RIP (Routing Information Protocol) allows a routing device to exchange routing information with other routers. The Direction field controls the sending and receiving of RIP packets. When set to:

•Both - the Switch will broadcast its routing table periodically and incorporate the RIP information that it receives.

•Incoming - the Switch will not send any RIP packets but will accept all RIP packets received.

•Outgoing - the Switch will send out RIP packets but will not accept any RIP packets received.

•None - the Switch will not send any RIP packets and will ignore any RIP packets received.

The Version field controls the format and the broadcasting method of the RIP packets that the Switch sends (it recognizes both formats when receiving). RIP-1is universally supported; but RIP-2 carries more information. RIP-1is probably adequate for most networks, unless you have an unusual network topology.

Both RIP-2Band RIP-2Msend the routing data in RIP-2 format; the difference being that RIP-2Buses subnet broadcasting while RIP-2Muses multicasting.

36.1.1 Administrative Distance

When two or more than two different routing protocols, such as RIP and OSPF provide multiple routes to the same destination, the Switch can use the administrative distance of the route to determine which routing protocol to use and add the route to the routing table.

The lower the administrative distance value is, the more preferable the routing protocol is. If two routes have the same administrative distance value, the Switch
