If this command is not used, then
<ipaddr>
defaults to 0.0.0.0, and this end cannot initiate the tunnel.
L2TP SET AUTHEN
Enables or disables authentication of the remote router during tunnel establishment using the CHAP secret, if it
exists. If the remote router tries to authenticate the local end during tunnel authentication, the local router will
always attempt to respond, provided a CHAP secret has been configured.
L2TP CALL
This command is primarily used for debugging purposes and it establishes a tunnel without creating a session.
L2TP SET CHAPSECRET

certain control packet information. The LAC and the LNS can share a
single
CHAP secret for a given tunnel.
