Configuring basic L2TP capabilities

Basic L2TP capability configuration includes the following tasks:
•
Enabling L2TP—L2TP must be enabled for L2TP configurations to take effect.
•
Creating an L2TP group—An L2TP group is intended to represent a group of parameters.
This enables not only flexible L2TP configuration on devices, but also one-to-one and
one-to-many networking applications for LACs and LNSs. An L2TP group has local significance
only. However, the relevant settings of the L2TP groups on the LAC and LNS must match. For
example, the local tunnel name configured on the LAC must match the tunnel peer name
configured on the LNS.
•
Configuring the local tunnel name—The local tunnel name identifies the tunnel at the local
end during tunnel negotiation between an LAC and an LNS.
To configure basic L2TP capabilities:
Step
1. Enter system view.
2. Enable L2TP.
3. Create an L2TP group,
specify its mode, and enter
its view.
4. Specify the local tunnel
name.

Configuring an LAC

An LAC establishes tunnels with LNSs and forwards packets between LNSs and remote systems.

Configuring an LAC to initiate tunneling requests for a user

This task configures an LAC to initiate tunneling requests to an LNS for a user. When the PPP user
information matches the specified user, the LAC determines that the PPP user is an L2TP user and
initiates tunneling requests to the LNS.
You can specify a user by configuring one of the following items:
•
Fully qualified name—The LAC initiates tunneling requests to the LNS only if the username of
a PPP user matches the configured fully qualified name.
•
Domain name—The LAC initiates tunneling requests to the LNS only if the ISP domain name
of a PPP user matches the configured domain name.
To configure an LAC to initiate tunneling requests for a user:
Step
1. Enter system view.
2. Enter L2TP group view in
LAC mode.
Command
system-view
l2tp enable
l2tp-group group-number mode
{ lac | lns }
tunnel name name
Command

Remarks
N/A
By default, L2TP is disabled.
By default, no L2TP group exists.
Specify the mode as lac on the
LAC side and as lns on the LNS
side.
Optional.
By default, the device name is
used.
