In the following figure, you are configuring a GRE tunnel. What is wrong with this configuration?

The network is unrouteable, since interface G0/1 on Router A is configured with a 192.168.1.0/24 network and interface G0/1 on Router B is configured with a 192.168.1.0/24. The route statement that needs to be configured will not pass any traffic since 192.168.1.0/24 is directly configured on both routers. The destination on Router A of the tunnel is correct, but the interface G0/1 on Router B is incorrectly addressed. The serial interfaces are on different addresses but most likely correspond to the IP network in the WAN cloud.
