By default, no source address or
source interface is configured for
the tunnel interface.
If you specify a source address, it
is used as the source IP address
of tunneled packets.
If you specify a source interface,
the primary IP address of this
interface is used as the source IP
address of tunneled packets.

Configuration example
Network requirements
As shown in Figure 129, the two subnets IPv4 group 1 and IPv4 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 129 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
