[RouterB] ipx route 1e 1f.a.a.a tick 30000 hop 15

Troubleshooting GRE The two interfaces at both ends of the tunnel are correctly configured and the ping operation is successful, but the ping operation between PC A and PC B fails.

Check whether there is a route passing through the Tunnel interface, that is, on Router A, the route to 10.2.0.0/16 passes through Tunnel0 interface; on Router B, the route to 10.1.0.0/16 passes through Tunnel0 interface (it is implemented by adding a static route).
