288 Chapter 7: Managing Address Spaces with NAT and IPv6
RIPng, instead of using the network command to identify which interfaces should run
RIPng, you use the command ipv6 rip tag enable in interface con?¬?guration mode to enable
RIPng on an interface. The tag parameter that you use for the ipv6 rip enable command
must match the tag parameter in the ipv6 router rip command.
Example: RIPng for IPv6 Configuration
Figure 7-18 shows a network of two routers. Router Y is connected to the default network.
On both Router X and Router Y, ???RT0??? is a tag that identi?¬?es the RIPng process. RIPng is
enabled on the ?¬?rst Ethernet interface of Router Y using the ipv6 rip RT0 enable
command. Router X shows that RIPng is enabled on both Ethernet interfaces using the ipv6
rip RT0 enable command.
Figure 7-18 RIPng Con?¬?guration Example
NOTE Enabling RIP on an interface dynamically creates a ???router rip??? process if
necessary.

Summary of Transitioning to IPv6
The following summarizes the key points that were discussed in this section:
?– IPv6 offers many additional bene?¬?ts to IPv4, including a larger address space, easier
address aggregation, and integrated security.
