RIPng (Routing Information Protocol Next Generation) is an extension of the original Routing Information Protocol (RIP) designed specifically for IPv6 networks. Let’s dive into the technical details:
- Metric and Updates:
- Like RIP for IPv4, RIPng uses hop count as the metric to measure the distance to a destination.
- It sends updates every 30 seconds.
- Message Format:
- RIPng messages use UDP port 521 and the multicast address FF02::9.
- Configuration:
- To enable RIPng, follow these steps:
- Enable RIPng using the global configuration command:
ipv6 router rip <tag>
. The<tag>
differentiates between multiple RIP processes. - Enable the routing protocol on an interface using:
ipv6 rip <tag> enable
. The<tag>
must match the one used in theipv6 router rip
command.
- Enable RIPng using the global configuration command:
Router(config)# ipv6 router rip router_1 Router(config)# int fa0/1 Router(config-if)# ipv6 rip router_1 enable
- To enable RIPng, follow these steps:
- Verification:
- To verify that routers are exchanging route information using RIPng, use the command:
show ipv6 route
.
- To verify that routers are exchanging route information using RIPng, use the command:
RIPng provides a simple and efficient way for routers within an IPv6 network to exchange routing information.
