Run the display ip routing-table command. If the route passing through the tunnel interface
exists in the routing table, the configuration succeeds. For example:
<Quidway> display ip routing-table
Route Flags: R - relay, D - download to fib

Run the ping -a source-ip-address dest-ip-address command, and you can find that the ping
from the local tunnel interface to the destination tunnel succeeds.
2.4 Configuring a GRE Tunnel Between CE and PE
Configuring a GRE tunnel between a CE and a PE enables the CE to access the public network
through the GRE tunnel.
2.4.1 Establishing the Configuration Task
Before configuring a GRE tunnel between a CE and a PE, familiarize yourself with the applicable
environment, complete the pre-configuration tasks, and obtain the required data. This can help
you complete the configuration task quickly and accurately.
