The configuration of RIPng is a little different from its predecessor, RIPv2. First of all, RIPng is IPv6 avare routing protocol and before RIPng Cisco configuration, IPv6 must be configured in your system.
In this article, we will configure RIPng Cisco according to the below topology.
Here, for Cisco RIPng configuration there are two steps. These steps are:
1) Enabling CEF, IPv6 and RIPng globally,
2) Enabling RIPng for the specific interface.
Firstly we will enable CEF with “ip cef” command and again we will enable IPv6 routing with “ipv6 unicast-routing” command. After this we need to create RIPng with a name by “ipv6 router rip ripname” command.
Router1# configure terminal Router1(config)# ip cef Router1(config)# ipv6 unicast-routing Router1(config)# ipv6 router rip CompanyNetworkRIP
Router2# configure terminal Router2(config)# ip cef Router2(config)# ipv6 unicast-routing Router2(config)# ipv6 router rip CompanyNetworkRIP
Router3# configure terminal Router3(config)# ip cef Router3(config)# ipv6 unicast-routing Router3(config)# ipv6 router rip CompanyNetworkRIP
After these, the second step is enabling the interfaces for RIPng. In RIPv2, networks are become RIP available via network command. But in RIPng, the configuration is done via interfaces not networks.
Router1(config)# interface Loopback0 Router1(config-if)# no ip address Router1(config-if)# ipv6 enable Router1(config-if)# ipv6 address 1111:A:A:A::1/128 Router1(config-if)# ipv6 rip CompanyNetworkRIP enable Router1(config-if)# exit
Router1(config)# interface FastEthernet0/0 Router1(config-if)# no ip address Router1(config-if)# duplex auto Router1(config-if)# speed auto Router1(config-if)# ipv6 enable Router1(config-if)# ipv6 address 1111:1:1:1::1/64 Router1(config-if)# ipv6 rip CompanyNetworkRIP enable
