| 4.2 |  | Configuring RIP v2 |
| 4.2.2 |  | Compatibility with RIP v1 |

The interface-level “compatibility switches” recommended by RFC 1723 are implemented in Cisco IOS with the commands ip rip send version and ip rip receive version.

> NewYork(config)#interface fastethernet0/0
> NewYork(config-if)#ip address 192.168.50.129 255.255.255.192
> NewYork(config-if)#ip rip send version 1
> NewYork(config-if)#ip rip receive version 1

> NewYork(config)#interface fastethernet0/1
> NewYork(config-if)#ip address 172.25.150.193 255.255.255.240
> NewYork(config-if)#ip rip send version 1 2

> NewYork(config)#interface fastethernet0/2
> NewYork(config-if)#ip address 172.25.150.225 225.255.255.240

> NewYork(config)#router rip
> NewYork(config-router)#version 2

Interface FastEthernet0/0 is configured to send and receive RIP v1 updates while FastEthernet0/1 is configured to send both version 1 and 2 updates. FastEthernet0/2 has no special configuration and therefore sends and receives version 2 by default.
