Configure a Directly Connected Static IPv6 Route

The directly connected static IPv6 route is the best solution in the routing when CEF is not working on the router. In the old Cisco IOs before 12.0 versions, this is the best solution to avoid recursive routing. This is also the best in point-to-point networks. It is also best an alternative to using the next-hop IPv6 address to specify the exit interface. The following figure illustrates the directly connected static IPv6 route configured on Router1 using the exit Interface.

Figure 2 illustrates the IPv6 routing table for Router1. When a packet is destined for 2001:AD10:110B::/64 network; Router1 looks in the routing table for a match and finds that; it can forward the packet out of its Fast Ethernet 0/0 interface. So, it is not required any other routing table lookups.

You can also verify the routing table looks different for the route configured with the next-hop IP address and an exit interface. Configuring a directly connected static route with an exit interface allows the routing table to resolve the exit interface in a single search instead of multiple searches. Therefore it resolves the recursive routing problem without using CEF.   The administrative distance is 1, for the directly connected IPv6 route.
