Configuring an LNS to accept L2TP tunneling requests from an LAC

When receiving a tunneling request, an LNS performs the following operations:

Determines whether to accept the tunneling request by checking whether the name of the tunnel peer (LAC) matches the one configured.
Determines the VT interface to be used for creating the VA interface.

To configure an LNS to accept L2TP tunneling requests from an LAC:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Enter L2TP group view in LNS mode.	l2tp-group group-number [ mode lns ]	N/A
3. Configure the LNS to accept tunneling requests from an LAC and specify the VT interface to be used for tunnel setup.	If the L2TP group number is 1:allow l2tp virtual-template virtual-template-number [ remote remote-name ] If the L2TP group number is not 1:allow l2tp virtual-template virtual-template-number remote remote-name	By default, an LNS denies tunneling requests from any LAC. If the L2TP group number is 1, the remote remote-name option is optional. If you do not specify this option, the LNS accepts tunneling requests from any LAC.

3. Configure the LNS to accept tunneling requests from an LAC and specify the VT interface to be used for tunnel setup.

If the L2TP group number is 1:allow l2tp virtual-template virtual-template-number [ remote remote-name ]
If the L2TP group number is not 1:allow l2tp virtual-template virtual-template-number remote remote-name

By default, an LNS denies tunneling requests from any LAC.

If the L2TP group number is 1, the remote remote-name option is optional. If you do not specify this option, the LNS accepts tunneling requests from any LAC.
