DVPN Configuration 215

Configuring the Tunnel

Interface

Configuring the encapsulation format

Before configuring other DVPN parameters, be sure to encapsulate the Tunnel

interface with UDP DVPN.

Perform the following configuration in Tunnel interface view on a client or a DVPN

server.

A Tunnel interface is encapsulated using GRE by default.

Configuring the type of the Tunnel interface

Configure the Tunnel interface as server or client type according to its location

(server side or client side).

Perform the following configuration in Tunnel interface view on a client or a DVPN

server.

A Tunnel interface is of client type by default.

Configuring register type for a DVPN client

You can only use the dvpn register-type command on the client. When

registering with the server, the client can ask the server to the data packet from

this client and notify the server not to send the registering information about this

client to other clients.

Perform the following configuration in Tunnel interface view on the client.

By default, the register type for the DVPN client is not configured.

Configuring the DVPN domain the Tunnel interface belongs to

You can configure the ID of the DVPN domain the Tunnel interface belongs to by

performing this operation. (Tunnel interfaces that belong to the same DVPN

domain have the same DVPN ID.)
