IP RIP Send Command on CISCO Router/Switch

Command

IP RIP Send

Use

This command is used tell RIP what version to sends its updates in for a specified interface. Can be sent in Version 1, Version 2, or both. Useful if you have a legacy host that runs RIP but only supports Version 1.

Syntax

Router(config-if)#ip rip send version <version> <version>

Example

IP RIP Send Command on CISCO Router/Switch 1

In this example, we will configure RIP on R2 to send RIPv1 and RIPv2 updates to R1. First, we will configure RIPv2 for all interfaces on R2.
Notice how RIPv2 only allows RIPv2 packets to be sent

R2(config)#router rip
R2(config-router)#version 2
R2(config-router)#no auto
R2(config-router)#network 0.0.0.0

R2(config)#do show ip protocols
Routing Protocol is “rip”
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
Sending updates every 30 seconds, next due in 23 seconds
Invalid after 180 seconds, hold down 180, flushed after 240
Redistributing: rip
Default version control: send version 2, receive version 2
Interface Send Recv Triggered RIP Key-chain
FastEthernet0/0 2 2
FastEthernet1/0 2 2
NVI0 2 2
Loopback0 2 2
Automatic network summarization is not in effect
Maximum path: 4
Routing for Networks:
0.0.0.0
Routing Information Sources:
Gateway Distance Last Update
10.2.2.3 120 00:00:02
Distance: (default is 120)

Next we will configure R1’s Fa0/0 to allow RIP to send either version 1 or version 2 packets.

R2(config-if)#int fa0/0

R2(config-if)#ip rip send version 1 2

Now RIP is able to send in both versions

R2(config-if)#do show ip protocols
Routing Protocol is “rip”
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
Sending updates every 30 seconds, next due in 25 seconds
Invalid after 180 seconds, hold down 180, flushed after 240
Redistributing: rip
Default version control: send version 2, receive version 2
Interface Send Recv Triggered RIP Key-chain
FastEthernet0/0 2 1 2
NVI0 2 2
Loopback0 2 2
Automatic network summarization is not in effect
Maximum path: 4
Routing for Networks:

Passive Interface(s):

10.1.1.1 120 00:00:02
