Checking The Configuration - Huawei Quidway S9300 Configuration Manual

2 GRE Configuration
In static route configuration, the destination address is the destination of the packet that is not
encapsulated by GRE, rather than the destination address of the tunnel. The next hop is the
address of the local tunnel interface.
Step 3 For configuration of dynamic routes, refer to the Quidway S9300 Terabit Routing Switch
Configuration Guide - IP Routing.
When configuring a dynamic routing protocol, you need to enable the protocol on both the tunnel
interface and the router interface connected to the private network. In addition, to ensure proper
routing, do not select the tunnel interface as the next hop to the destination physical address of
the tunnel.

Example
If the configuration is successful, you can see that the tunnel interface is Up by running the
display interface tunnel command on the two ends of the tunnel. The following is an example:
<Quidway> display interface Tunnel 1/0/0
Tunnel1/0/0 current state : UP
Line protocol current state : UP
Description:HUAWEI, Quidway Series, Tunnel1/0/0 Interface
Route Port,The Maximum Transmit Unit is 1500
Internet Address is 40.1.1.1/24
Encapsulation is TUNNEL, loopback not set
Tunnel source 118.118.1.1 (Vlanif11), destination 3.3.3.9
Tunnel protocol/transport GRE/IP, key 0x2333
keepalive disabled
Checksumming of packets enabled
Output queue : (Urgent queue : Size/Length/Discards)
Output queue : (Protocol queue : Size/Length/Discards) 0/1000/0
Output queue : (FIFO queue : Size/Length/Discards)

NOTE
In actual configuration, you can select either step 2 or step 3 according to the application type.
Run the display interface tunnel [ interface-number ] command to view the operation
status of the interface.
Run the display ip routing-table command to view the routing table.
Run the ping -a source-ip-address destination-ip-address command to check whether the
two ends of the tunnel can communicate with each other.
