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
Router A and Router 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 Router A and Router B can reach each other.
1. Configure Router A:
# Create a tunnel interface Tunnel 0, and specify the tunnel mode as GRE/IPv4.
<RouterA> system-view
[RouterA] interface tunnel 0 mode gre
# Configure an IP address for the tunnel interface.
[RouterA-Tunnel0] ip address 10.1.2.1 255.255.255.0
# Configure the source address of the tunnel interface as the IP address of GigabitEthernet
2/1/2 on Router A.
[RouterA-Tunnel0] source 1.1.1.1
# Configure the destination address of the tunnel interface as the IP address of GigabitEthernet
2/1/2 on Router B.
[RouterA-Tunnel0] destination 2.2.2.2
[RouterA-Tunnel0] quit
# Configure a static route from Router A through the tunnel interface to Group 2.
[RouterA] ip route-static 10.1.3.0 255.255.255.0 tunnel 0
2. Configure Router B:
# Create tunnel interface Tunnel 0 and specify the tunnel mode as GRE/IPv4.
<RouterB> system-view
[RouterB] interface tunnel 0 mode gre
# Configure an IP address for the tunnel interface.
