Step Command Remarks

6. Configure a destination

address for the tunnel

interface.

destination ip-address

By default, no destination address is

configured for the tunnel.

Configuration example

Network requirements

As shown in Figure 104, the two subnets Group 1 and Group 2 use private IPv4 addresses. Configure an

IPv4 over IPv4 tunnel between Router A and Router B to make the two subnets reachable to each other.

Figure 104 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 GigabitEthernet 2/0/1.

<RouterA> system-view

[RouterA] interface gigabitethernet 2/0/1

[RouterA-GigabitEthernet2/0/1] ip address 10.1.1.1 255.255.255.0

[RouterA-GigabitEthernet2/0/1] quit

# Specify an IPv4 address for GigabitEthernet 2/0/2, the physical interface of the tunnel.

[RouterA] interface gigabitethernet 2/0/2

[RouterA-GigabitEthernet2/0/2] ip address 2.1.1.1 255.255.255.0

[RouterA-GigabitEthernet2/0/2] quit

# Create interface Tunnel 1.

[RouterA] interface tunnel 1

# Specify an IPv4 address for interface Tunnel 1.

[RouterA-Tunnel1] ip address 10.1.2.1 255.255.255.0

# Configure the tunnel encapsulation mode as IPv4 over IPv4.

[RouterA-Tunnel1] tunnel-protocol ipv4-ipv4

# Specify the IP address of GigabitEthernet 2/0/2 as the source address for interface Tunnel 1.
