string of 1 to 15 characters. &<1-6> means that you can specify the argument for up to 6 times.

Description Use the ipsec profile command to configure to reference an IPSec profile on a DVPN tunnel interface.

Use the undo ipsec profile command to cancel the reference of an IPSec profile on a DVPN tunnel interface.

By default, no IPSec profile exists. That is, DVPN tunnels are not protected.

Note that:

IPSec profiles are applicable only for the interfaces of DVPN-type tunnels.

A DVPN tunnel interface can reference only one IPSec profile.

You need cancel the currently referenced IPSec profile on a DVPN tunnel interface before referencing a new one.

Related command: ipsec profile (system view) and interface tunnel on page 884.

Example # Specify to reference IPSec profile dvpnprofile on DVPN tunnel interface Tunnel0 to protect the DVPN tunnel.

<Sysname> system-view [Sysname] interface tunnel 0

[Sysname-Tunnel0] tunnel-protocol dvpn udp

[Sysname-Tunnel0] ipsec profile dvpnprofile
