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 Router A and Router C to view whether Router A
has a route over tunnel 0 to 10.2.0.0/16 and whether Router 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.
Take Router A as an example:
[RouterA] ip route-static 10.2.0.0 255.255.0.0 tunnel 1
