Command
IP RIP Receive
Use
This command is used tell RIP what version to receive its updates in for a specified interface. Updates can be sent in Version 1, Version 2, or both.
It is useful if you have a legacy host that runs RIP but only supports Version 1.
Syntax
Router(config-if)#ip rip receive version <version> <version>
Example

In this example, we will configure RIP on R2 to receive R1’s RIPv1 updates.
First, we will configure RIPv1 for all interfaces on R1. Notice that, by default, RIPv1 will allow RIPv2 packets to be received.
R1(config)#router rip R1(config-router)#do show ip protocol |
Now we will configure RIPv2 for all interfaces on R2. Notice how RIPv2 only allows RIPv2 packets to be received
R2(config)#router rip R2(config)#do show ip protocols |
Currently, we are not receiving any routes from R1 due to the difference in versions.
R2(config-if)#do show ip route rip R2(config-if)# |
Next we will configure R1’s Fa0/0 to allow RIP to receive either version 1 or version 2 packets.
R2(config-if)#int fa0/0 R2(config-if)#ip rip receive version 1 2 |
Now we have entries in the routing table.
R2(config-if)#do show ip route rip |
