Configuring An Lns; Creating A Vt Interface; Configuring An Lns To Accept L2Tp Tunneling Requests From A Specified Lac - HP VSR1000 Layer 2 - Wan Access Configuration Manual

Step
9. (Optional.) Restore the default
settings for the interface.
10. (Optional.) Bring up the
interface.

Configuring an LNS

An LNS responds to the tunneling requests from an LAC, authenticates users, and assigns IP addresses to
users.

Creating a VT interface

After an L2TP session is established, a virtual access (VA) interface is needed for data exchange with the
peer. The system will dynamically create VA interfaces based on the parameters of the virtual template
(VT) interface. To configure an LNS, first create a VT interface and configure parameters for it. These
parameters include the following:
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 an LNS to accept L2TP tunneling requests from a
specified LAC
When receiving a tunneling request, an LNS determines whether to accept the tunneling request by
checking whether the name of the tunnel peer (LAC) matches the one configured, and determines the VT
interface to be used for creating the VA interface.
To configure an LNS to accept L2TP tunneling requests from a specified LAC:
Step
1. Enter system view.
2. Enter L2TP group view in LNS
mode.
3. Configure the LNS to accept
tunneling requests from a
specified LAC and specify the
VT interface to use for tunnel
setup.

•
If the L2TP group number is 1:

If the L2TP group number is
not 1:

Remarks
N/A
By default, an interface is up.
Remarks

N/A
Use either command.
By default, an LNS denies
tunneling requests from any LACs.
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 LACs.
