In Figure 1, the show ipv6 route static command output displays the contents of the routing table.
Unlike IPv4, IPv6 does not explicitly state that the default IPv6 is the Gateway of Last Resort.
The key to this configuration is the ::/0 mask. Recall that the ipv6 prefix-length in a routing table determines how many bits must match between the destination IP address of the packet and the route in the routing table. The ::/0 mask indicates that none of the bits are required to match. As long as a more specific match does not exist, the default static IPv6 route matches all packets.
Figure 2 displays a successful ping to the R3 LAN interface.
