Configuration procedure
NOTE:
Before the configuration, make sure that Device A and Device B are reachable to each other.
Step1 Configure Device A
# Configure an IPv4 address for interface GigabitEthernet 1/1.
system-view
[DeviceA] interface gigabitethernet 1/1
[DeviceA-GigabitEthernet1/1] ip address 10.1.1.1 255.255.255.0
[DeviceA-GigabitEthernet1/1] quit
# Configure an IPv4 address for interface GigabitEthernet 2/0, the physical interface of the tunnel.
[DeviceA] interface gigabitethernet 2/0
[DeviceA-GigabitEthernet2/0] ip address 1.1.1.1 255.255.255.0
[DeviceA-GigabitEthernet2/0] quit
# Create an interface named Tunnel 0.
[DeviceA] interface tunnel 0
# Configure an IPv4 address for interface Tunnel 0.
[DeviceA-Tunnel0] ip address 10.1.2.1 255.255.255.0
# Configure the tunnel encapsulation mode as GRE over IPv4.
[DeviceA-Tunnel0] tunnel-protocol gre
# Configure the source address of interface Tunnel 0 to be the IP address of GigabitEthernet 2/0.
[DeviceA-Tunnel0] source 1.1.1.1
# Configure the destination address of interface Tunnel 0 to be the IP address of GigabitEthernet 2/1 on
Device B.
[DeviceA-Tunnel0] destination 2.2.2.2
[DeviceA-Tunnel0] quit
# Configure a static route from Device A through interface Tunnel 0 to Group 2.
[DeviceA] ip route-static 10.1.3.0 255.255.255.0 tunnel 0
Step2 Configure Device B
# Configure an IPv4 address for interface GigabitEthernet 1/1.
system-view
[DeviceB] interface gigabitethernet 1/1
[DeviceB-GigabitEthernet1/1] ip address 10.1.3.1 255.255.255.0
[DeviceB-GigabitEthernet1/1] quit
# Configure an IPv4 address for interface GigabitEthernet 2/1, the physical interface of the tunnel.
