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
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: 0.0.0.0 Passive Interface(s): FastEthernet1/0 Routing Information Sources: Gateway Distance Last Update 10.2.2.3 120 00:06:04 10.1.1.1 120 00:00:02 Distance: (default is 120)
