Configuring RIP for IPv6
The RIP standard for IPv6, or RIPng, is built upon the original RIP standard, which is why it is important to have a thorough understanding of the original protocol. However, RIPng does offer a few enhancements to the original RIP standard; these include, of course, full support for the IPv6 standard and prefixes as well as support for an all-routers RIP multicast address group for routing update messages to all RIPng routers. This offers an alternative to the broadcast messaging solution used by the previous implementations of RIP.
Basic IPv6 RIP Configuration
Although IPv6 RIP is very similar to its predecessor RIP, some striking differences exist between the two protocols when it comes down to their actual configuration. The first of these differences is apparent when enabling the RIP routing process. In the previous release, you started the RIP process by giving the command Router rip in global configuration mode followed by specifying the networks that would be included in the RIP routing domain by typing the network command. The configuration for IPv6 RIP is similar, but not identical. To enable the RIP routing process for IPv6, the ipv6 router rip < word> command is used. The word command is actually a process identifier that is a user-defined series of numbers or letters that identify the specific RIP process. This enables the router to run multiple segregated RIP processes on the same router. To add specific networks to the RIPng routing domain, the
