Usage guidelines
When you start a PPP session, a client of NAS-initialized VPN will first negotiate with the NAS for LCP
parameters. If the negotiation succeeds, the NAS initializes a tunnel and then transfers the negotiated
results to the LNS. Then the LNS verifies whether the client is valid, depending on the proxy authentication
information. You can use the mandatory-lcp command to force the LNS to perform LCP re-negotiation for
the client. In this case, the proxy authentication information of the NAS will be neglected. Some PPP
clients do not support LCP re-negotiation. In this case, the LCP re-negotiation will fail.
Examples
# Perform LCP negotiation by force.
