Description
Use the mandatory-lcp command to allow LNS and client to renegotiate Link Control
Protocol (LCP) between them.
Use the undo mandatory-lcp command to disable LCP renegotiation.
By default, LCP is not renegotiated.
Concerning NAS-Initialized VPN client, PPP negotiation will be first performed with
Network Access Server (NAS) at the beginning of a PPP session. If the negotiation is
successful, the access server will initiate the tunnel connection and transmit the
information collected during the negotiation to LNS. LNS will judge whether the user is
legal based on the information. The mandatory-lcp command can be used to force
LNS and client to renegotiate LCP. In this case, NAS agent authentication information is
ignored. If PPP clients do not support LCP renegotiation, LCP renegotiation will fail.
Related command: mandatory-chap.

# Enable LCP renegotiation.
