The example in Figure 1 shows the configuration steps for the directly connected interfaces of R1 with the indicated IPv6 addresses. Notice the Layer 1 and Layer 2 informational messages generated as each interface is configured and activated.

The show ipv6 route command shown in Figure 2 is used to verify that IPv6 networks and specific IPv6 interface addresses have been installed in the IPv6 routing table. Like IPv4, a ‘C’ next to a route indicates that this is a directly connected network. An ‘L’ indicates the local route. In an IPv6 network, the local route has a /128 prefix. Local routes are used by the routing table to efficiently process packets with a destination address of the interface of the router.

Notice that there is also a route installed to the FF00::/8 network. This route is required for multicast routing.

Figure 3 displays how the show ipv6 route command can be combined with a specific network destination to display the details of how that route was learned by the router.

Figure 4 displays how connectivity to R2 can be verified using the ping command.

In Figure 5, notice what happens when the G0/0 LAN interface of R2 is the target of the ping command. The pings are unsuccessful. This is because R1 does not have an entry in the routing table to reach the 2001:DB8:ACAD:4::/64 network.

R1 requires additional information to reach a remote network. Remote network route entries can be added to the routing table using either:
