Configuring A Va Pool; Configuring An Lns To Accept L2Tp Tunneling Requests From A Specific Lac - HP MSR Router Series Wan Access Configuration Manual

(VT) interface. To configure an LNS, first create a VT interface and configure the following parameters for
it:
Interface IP address.
•
Authentication mode for PPP users.
•
IP addresses allocated by the LNS to PPP users.
•
For information about configuring VT interfaces, see "Configuring PPP and MP" and Layer 3—IP Services
Configuration Guide.

Configuring a VA pool

A VA pool contains a group of VA interfaces. You can configure a VA pool to improve the performance
of establishing or terminating L2TP connections. The LNS selects a VA interface from the pool for a
requesting user and releases the VA interface when the user goes offline. When a VA pool is exhausted,
the system creates a VA interface for an L2TP connection and deletes it when the user goes offline.
Configuration guidelines
When you configure a VA pool, follow these guidelines:
A VT interface can be associated with only one VA pool. To change the capacity of a VA pool,
•
delete the previous configuration and reconfigure the VA pool.
• Creating or deleting a VA pool takes time. During the process of creating or deleting a VA pool,
users can come online or go offline, but the VA pool does not take effect.
The system might create a VA pool that contains VA interfaces less than the specified number
•
because of insufficient resources. To view the number of available VA interfaces and the current
state of the VA pool, use the display l2tp va-pool command.
• Create a VA pool with an appropriate capacity, because a VA pool occupies much system memory.
Deleting a VA pool does not log off the users who are using VA interfaces in the VA pool.
•
Configuration procedure
To configure a VA pool:
Step
1. Enter system view.
2. Create a VA pool.
Configuring an LNS to accept L2TP tunneling requests from a
specific 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 a specific LAC:
Command
system-view
l2tp virtual-template
template-number va-pool va-volume
83
Remarks
N/A
By default, no VA pool exists.
