Chapter 2 RIP Configuration Commands

3Com Corporation

2-21

Parameter

1: Interface version is RIP-1.

2: Interface version is RIP-2. By default, multicast is used.

broadcast: Transmission mode of RIP-2 packet is broadcast.

multicast: Transmission mode of RIP-2 packet is multicast.

Description

Use the rip version command to configure the version of RIP packets on an interface.

Use the undo rip version command to restore the default value of RIP packet version

on the interface.

By default, the interface RIP version is RIP-1.

RIP-2 has 2 transmission modes: broadcast and multicast. Multicast is the default

mode. The multicast address in RIP-2 is 224.0.0.9. One of the advantages of multicast

mode is that the hosts that do not run RIP in this network will not receive the broadcast

packets. Additionally, hosts running RIP-1 will be prevented from receiving and

processing the RIP-2 routes with subnet masks.

When the interface specifies the use of RIP-1, only RIP-1 and RIP-2 broadcast packets

will be received. In this case, RIP-2 multicast packets will be rejected. When the

interface is specified to use RIP-2 multicast, only RIP-2 multicast packets and RIP-2

broadcast packets will be received. In this case, RIP-1 packets will be rejected.

Example

# Configure the interface serial1/0/0 as RIP-2 broadcast mode.
