| 4.1.1 |  | RIP v2 operation |

All of the operational procedures, timers, and stability functions of RIP v1 remain the same in RIP v2, with the exception of the broadcast updates. RIP v2 updates to other RIP v2 inter-routers by multicasting. This occurs by using the reserved Class D address 224.0.0.9. The advantage of multicasting is that devices on the local network that are not concerned with RIP routing do not have to spend time unwrapping broadcast packets from the router. The multicast updates are examined further in the section, Compatibility with RIP v1.

After a look at how the RIP message format accommodates the version 2 extensions, this section focuses on the operation and benefits of these additional features.
