Configuring an IPv4 over IPv4 GRE tunnel

Network requirements
As shown in
use private network addresses and belong to the same VPN. Establish a GRE tunnel between
Switch A and Switch B to interconnect the two private IPv4 networks Group 1 and Group 2.

Configuration procedure
Before performing the following configuration, configure an IP address for each interface, and make
sure Switch A and Switch B can reach each other.
1. Configure Switch A:
# Create service loopback group 1, and configure the service type as tunnel.
<SwitchA> system-view
[SwitchA] service-loopback group 1 type tunnel
# Add port GigabitEthernet 1/0/3 to service loopback group 1.
[SwitchA] interface gigabitethernet 1/0/3
[SwitchA-GigabitEthernet1/0/3] port service-loopback group 1
[SwitchA-GigabitEthernet1/0/3] quit
# Create a tunnel interface Tunnel 1, and specify the tunnel mode as GRE/IPv4.
[SwitchA] interface tunnel 1 mode gre
# Configure an IP address for the tunnel interface.
[SwitchA-Tunnel1] ip address 10.1.2.1 255.255.255.0
# Configure the source address of tunnel interface as the IP address of VLAN-interface 101 on
Switch A.
