Example
The following command defines the default list of authentication
methods for PPP users. Because this is the default list, it applies
to all PPP users, even if there is no login authentication
command. The router attempts to use the
tacacs+
method for authentication; if the device
cannot contact the TACACS+ server, no other authentication is
attempted, and the connection is rejected.
