3.2.2 Creating Virtual Tunnel Interface
Perform the following task in global configuration mode.
Table VPN-3-1 Create virtual tunnel interface
Operation Command

designated. The source address and destination address of tunnel interface uniquel y
identifies a channel.
Perform the following setting in tunnel interface configuration m ode.
Table VPN-3-2 Designate the source address of tunnel interface
Operation Command
Designate the source address of tunnel interface. tunnel source ip-address
Cancel the source address of tunnel interface. no tunnel source
3.2.4 Setting the Destination Address of Tunnel Interface
After tunnel interface is established, the destination address of tunne l channe l should
be designated. The source address and destination address of tunnel interface
uniquely identifies a channel.
Perform the following setting in tunnel interface configuration m ode.
Table VPN-3-3 Designate the destination address of tunnel interface
Operation Command
