4.4 Configuring LNS
After receiving a tunnel setup request from an LAC, an LNS checks the authentication method
and determines whether to allow the LAC to set up an L2TP tunnel.
4.4.1 Establishing the Configuration Task
Before configuring an LNS, familiarize yourself with the applicable environment, complete the
pre-configuration tasks, and obtain the required data. This can help you complete the
configuration task quickly and accurately.
Applicable Environment
An LNS offers different virtual templates to receive the tunnel-establishing requests from
different LACs. After receiving one of these requests, the LNS needs to check whether the name
of the LAC (remote end) are valid, and then decide whether to permit the remote end to establish
a tunnel.
After an LAC performs the user authentication, an LNS can re-authenticates the user. That is,
the user is authenticated twice. One is on the LAC, and the other is on the LNS.
After a user passes the authentication on the LNS, the user can communicate with the LNS. If
the user authentication on the LNS fails, L2TP is notified to remove the L2TP connection. In
