ipv6-address: Specifies the tunnel source IPv6 address.
interface-type interface-number: Specifies the source interface. The interface must be up and must have
an IP address.
Usage guidelines
The specified source address or the address of the specified source interface is used as the source
address of tunneled packets. To display the configured tunnel source address, use the display interface
tunnel command.
The source address of the local tunnel interface must be the destination address of the peer tunnel
interface, and vice versa.
If you use this command multiple times, the most recent configuration takes effect.
You cannot specify the tunnel interface of the DS-Lite tunnel on the AFTR as the source interface.
Examples
# Set the interface GigabitEthernet 2/1/1 as the source interface of the interface Tunnel 1.
