Parameter ip-address: Source IPv4 address of a tunnel interface.

ip-address: Source IPv6 address of a tunnel interface.

interface-typeinterface-number: Specifies an interface. The interface types include Ethernet, serial, ATM, tunnel, and loopback.

Description Use the source command to specify a source address for a tunnel interface.

Use the undo source command to remove the configured source IP address.

By default, no source address is configured for a tunnel interface.

Note that:

■The source address of a tunnel interface is the address of the interface sending packets and is usually the destination address of the peer tunnel interface.

■Two or more tunnel interfaces using the same encapsulation protocol must have different source addresses and destination addresses.

Related command: interface tunnel and destination.

Example # Configure the interface tunnel 5. The actual outgoing interface encapsulating packets is Serial2/0 (192.100.1.1).

<Sysname> system-view [Sysname] interface tunnel 5 [Sysname-Tunnel5] source 192.100.1.1

Or

<Sysname> system-view [Sysname] interface tunnel 5 [Sysname-Tunnel5] source serial 2/0
