4.3.2 Configuring an L2TP Connection on LAC Side

After receiving a call from an LAC client, an LAC sends a connection request to an LNS in the
configuration sequence of the LNSs. If receiving a response from an LNS, the LNS becomes
the peer of the L2TP tunnel.

4.3.3 (Optional) Configuring LAC Auto-Dial

The router initiates virtual private dial-up network (VPDN) dialup and serves as a PPP client
and LAC.
Context
Enterprises expect virtual private networks (VPNs) to be constructed between the headquarters
and branches. The VPN construction costs, however, are high if the enterprises lease resources
from carriers. The VPDN technology allows an enterprise to construct a VPN, and the carrier
needs to provide Internet access for the enterprise. The investments are lowered. Branch routers
establish the VPDN network by dialing up and serve as PPP clients and LACs.
Perform the following steps on the router.
Procedure
Step 1 Run:
system-view
The system view is displayed.
