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").
