The configurations of S9300-B and S9300-C are similar to the configuration of S9300-A, and
are not mentioned here.
Step 2 Configure IGP on the VPN backbone network.
# Configure S9300-A.
[S9300-A] ospf 1
[S9300-A-ospf-1] area 0
[S9300-A-ospf-1-area-0.0.0.0] network 20.1.1.0 0.0.0.255
[S9300-A-ospf-1-area-0.0.0.0] quit
[S9300-A-ospf-1] quit
The configurations of S9300-B and S9300-C are similar to the configuration of S9300-A, and
are not mentioned here.
# Run the display ip routing-table command on S9300-A and S9300-C. You can find that they
learn the OSPF routes destined for the network segment of the peer.
# Take S9300-A for example. The information is displayed as follows:

Step 3 Configure the tunnel interface.
# Configure S9300-A.
[S9300A] interface tunnel 1/0/1
[S9300-A-Tunnel1/0/1] tunnel-protocol gre
[S9300-A-Tunnel1/0/1] ip address 40.1.1.1 255.255.255.0
[S9300-A-Tunnel1/0/1] source 20.1.1.1
[S9300-A-Tunnel1/0/1] destination 30.1.1.2
[S9300-A-Tunnel1/0/1] quit
# Configure S9300-C.
[S9300-C] interface tunnel 1/0/1
[S9300-C-Tunnel1/0/1] tunnel-protocol gre
[S9300-C-Tunnel1/0/1] ip address 40.1.1.2 255.255.255.0
[S9300-C-Tunnel1/0/1] source 30.1.1.2
[S9300-C-Tunnel1/0/1] destination 20.1.1.1
[S9300-C-Tunnel1/0/1] quit
# After the configuration, the status of tunnel interfaces is Up, and the tunnel interfaces can ping
each other.
# Take S9300-A for example. The information is displayed as follows:
