GRE over IPv4 tunnel configuration example

Network requirements
Group 1 and Group 2 are two private IPv4 networks. The two networks both use private network
addresses and belong to the same VPN. Configure a GRE tunnel between Switch A and Switch B so the
two private IPv4 networks can communicate with each other.

Configuration procedure
Before the following configurations, 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 Ten-GigabitEthernet1/1/5 to service loopback group 1.
[SwitchA] interface Ten-GigabitEthernet1/1/5
[SwitchA-Ten-GigabitEthernet1/1/5] port service-loopback group 1
[SwitchA-Ten-GigabitEthernet1/1/5] quit
# Create a tunnel interface Tunnel 1, and specify the tunnel mode as GRE over 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
