Protocols And Standards; Command And Hardware Compatibility; L2Tp Configuration Task List - HPE FlexNetwork MSR series Configuration Manual

L2TP tunnel sharing—Different users can share the same L2TP tunnel between the LAC

and the LTS. The LTS distributes data of different users to different LNSs.

L2TP configuration task list

When you configure L2TP, perform the following tasks:
1. Determine the network devices needed according to the networking environment.
For NAS-initiated mode and LAC-auto-initiated mode, configure both the LAC and the LNS.

For client-initiated mode, you only need to configure the LNS.

2. Configure the devices based on the intended role (LAC or LNS) on the network.
To configure a device as an LAC in NAS-initiated or LAC-auto-initiated mode, complete the following
tasks:
