Huawei quidway s7700 - Checking the Configuration

The system view is displayed.
Step 2 Run:
interface tunnel interface-number
The tunnel interface is created and the tunnel interface view is displayed.
Step 3 Run:
ip binding vpn-instance vpn-instance-name
Bind the GRE tunnel with the VPN instance.
NOTE
The running of the ip binding vpn-instance command on a tunnel interface can delete the Layer 3 attributes,
such as the IP address and routing protocol. If these Layer 3 attributes are still required, you need to
configure them again.
Step 4 Choose one of the following commands to configure the IP address of the tunnel interface.
l Run the ip address ip-address { mask | mask-length } [ sub ] command to assign an IP address
to the tunnel interface.
l Run the ip address unnumbered interface interface-type interface-number command to
configure IP unnumbered for the tunnel interface.

2.4.5 Checking the Configuration
After a GRE tunnel is set up between a CE and a PE, you can view routes to a specified VPN.
Prerequisite
The GRE tunnel between the CE and the PE is fully configured.
Procedure
l Run the display interface tunnel [ interface-number ] command to check the working
mode of the tunnel interface.
l Run the display ip routing-table vpn-instance vpn-instance-name command to check the
VPN routing table on the PE.
l Run the display ip routing-table command to check the routing table on the CE.
l Run the ping -a source-ip-address host command to check whether two ends of the tunnel
can ping each other successfully.
----End
Example
Run the display interface tunnel command on two ends of the tunnel. If the tunnel interface is
Up, it means that the configuration succeeds. Take the display on the PE as an example:
<Quidway> display interface Tunnel 1/0/0
Tunnel1/0/0 current state : UP
Line protocol current state : UP
Last line protocol up time : 2009-04-19 18:38:07
