Configuring AAA authentication on an LNS

After you configure AAA authentication on an LNS, the LNS can authenticate the usernames and passwords of remote access users. If a user passes AAA authentication, the user can communicate with the LNS to access the private network.

Configure AAA authentication on the LNS in one of the following cases:

• LCP renegotiation is not configured in NAS-initiated mode.

• The VT interface is configured with PPP user authentication and LCP renegotiation is configured in NAS-initiated mode.

• The VT interface is configured with PPP user authentication in client-initiated mode or LAC-auto-initiated mode.

LNS side AAA configurations are similar to those on an LAC (see "Configuring AAA authentication on an LAC").
