| In this scenario
(shown in the main figure and the RouterC#show ip route
command output), the link
between router A and router C has failed. Router C has converged on
the path via router B for its route to the gateway of last resort
network (10.0.0.0). 10.0.0.0 is now known via the next-hop address
of 168.71.7.2 (the router B serial 1). Because the local domain
default route of router C (168.71.0.0) is a static route to network
10.0.0.0, it works on the new path for 10.0.0.0 via router B as
well.
