Network requirements
As shown in
IPv4 over IPv4 tunnel between Router A and Router B to make the two subnets reachable to each other.
Figure 107 Network diagram
Configuration procedure
Make sure Router A and Router B can reach each other through IPv4.
Configure Router A:
•
# Specify an IPv4 address for Ethernet 1/1.
<RouterA> system-view
[RouterA] interface ethernet 1/1
[RouterA-Ethernet1/1] ip address 10.1.1.1 255.255.255.0
[RouterA-Ethernet1/1] quit
# Specify an IPv4 address for Serial 2/0, which is the physical interface of the tunnel.
[RouterA] interface serial 2/0
[RouterA-Serial2/0] ip address 2.1.1.1 255.255.255.0
[RouterA-Serial2/0] quit
# Create an IPv4 over IPv4 tunnel interface tunnel 1.
[RouterA] interface tunnel 1 mode ipv4-ipv4
# Specify an IPv4 address for the tunnel interface.
[RouterA-Tunnel1] ip address 10.1.2.1 255.255.255.0
# Specify the IP address of Serial 2/0 as the source address for the tunnel interface.
[RouterA-Tunnel1] source 2.1.1.1
# Specify the IP address of Serial 2/0 on Router B as the destination address for the tunnel
interface.
[RouterA-Tunnel1] destination 3.1.1.1
[RouterA-Tunnel1] quit
# Configure a static route destined for the IP network Group 2 through the tunnel interface.
[RouterA] ip route-static 10.1.3.0 255.255.255.0 tunnel 1
Configure Router B:
•
# Specify an IPv4 address for Ethernet 1/1.
<RouterB> system-view
[RouterB] interface ethernet 1/1
[RouterB-Ethernet1/1] ip address 10.1.3.1 255.255.255.0
Figure 107, the two subnets Group 1 and Group 2 use private IPv4 addresses. Configure an
