Step 3 Configure the tunnel interface.
# Configure Switch A.
[SwitchA] interface tunnel 1/0/1
[SwitchA-Tunnel1/0/1] tunnel-protocol gre
[SwitchA-Tunnel1/0/1] ip address 40.1.1.1 255.255.255.0
[SwitchA-Tunnel1/0/1] source 20.1.1.1
[SwitchA-Tunnel1/0/1] destination 30.1.1.2
[SwitchA-Tunnel1/0/1] quit
# Configure Switch C.
[SwitchC] interface tunnel 1/0/1
[SwitchC-Tunnel1/0/1] tunnel-protocol gre
[SwitchC-Tunnel1/0/1] ip address 40.1.1.2 255.255.255.0
[SwitchC-Tunnel1/0/1] source 30.1.1.2
[SwitchC-Tunnel1/0/1] destination 20.1.1.1
[SwitchC-Tunnel1/0/1] quit
# After the configuration, the status of tunnel interfaces is Up, and the tunnel interfaces can ping
each other.
# Take Switch A for example. The information is displayed as follows:
[SwitchA] ping -a 40.1.1.1 40.1.1.2
PING 40.1.1.2: 56
--- 40.1.1.2 ping statistics ---
Step 4 Configure static routes.
# Configure Switch A.
[SwitchA] ip route-static 10.2.1.0 255.255.255.0 tunnel 1/0/1
# Configure Switch C.
[SwitchC] ip route-static 10.1.1.0 255.255.255.0 tunnel 1/0/1
# Run the display ip routing-table command on Switch A and Switch C. You can see the static
route from the tunnel interface to the use-side network segment of the peer.
# Take Switch A for example. The information is displayed as follows:
[SwitchA] display ip routing-table
