Symptom
The interfaces at both ends of the tunnel are configured correctly and can ping each other, but Host A
and Host B cannot ping each other.
Solution
Execute the display ip routing-table command on Device A and Device C to view whether Device
1.
A has a route over tunnel 0 to 10.2.0.0/16 and whether Device C has a route over tunnel 0 to
10.1.0.0/16.
If such a route does not exist, execute the ip route-static command in system view to add the route.
2.
Take Device A as an example:
[DeviceA] ip route-static 10.2.0.0 255.255.0.0 tunnel 0
