3.2.4 Troubleshooting procedure
The steps of troubleshooting are as follows:
Step 1 Check that reachable routes exist between CEs.
On the local CE, ping the remote CE.
If the ping is successful, it indicates that reachable routes exist between CEs and rules out
the route problem between CEs. The section between VPN user PCs and CE can be faulty.
Check for reachable routes between them. If no reachable route is available, add the route.
