OSPFv3 Configuration
OSPFv3 is a new version of OSPF based on RFC 5340, which brings support for IPv6.
Unlike EIGRP, OSPFv3 requires a separate configuration stanza, router ospfv3 for IPv6
configurations. OSPFv3 leverages a separate feature than OSPFv2, feature ospfv3. IPv6
configuration elements for OSPF features discussed earlier in this chapter, such as
summarization and redistribution, follow similar configuration guidelines; however, they are
outside the scope of this book. This section focuses on basic OSPFv3 configuration and
verification.
Similar to OSPFv2, enabling OSPFv3 is a multistep process. The first step in OSPFv3
configuration is to enable the feature by executing the feature ospfv3 command. The
process of enabling this specific feature is the same as discussed earlier in this chapter for
OSPFv2. After the feature is enabled, the next step in the process is to configure the
OSPFv3 router process. It is also mandatory to configure a router-id as part of the
configuration process, as shown in Example 3-69.

Enter configuration commands, one per line. End with
CNTL/Z.
Congo(config)# router ospfv3 DataCenter1
Congo(config-router)# router-id 192.168.1.1
Now that the feature, routing process, and router-id have been configured, the next step is to
add IPv6-enabled interfaces to the OSPFv3 process.
Example 3-70 shows the addition of an SVI to the OSPFv3 DataCenter1 and verification
that the configuration was successful.
