L2TP configuration task list

When you configure L2TP, perform the following tasks:
Determine the network devices needed according to the networking environment.
1.
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:
