If mandatory CHAP authentication is configured on the LNS, you need to
configure local users and their passwords.
An LNS determines whether a remote dial-up user is a valid VPN user by checking
whether the username and password of the user match those configured on the
LNS itself. After the authentication succeeds, the VPN user can communicate with
the LNS. Otherwise, the LNS will notify the L2TP of removing the L2TP tunnel.
The username for the authentication on the LNS may be in two types of formats:
The username registered by the VPN user.
■
The username registered by the VPN user plus the domain name.
■
These configurations are optional on the LNS. For detailed configuration
information, refer to
Passwords" on page
According to RFC2661, the ACCM AVP is for the LNS to notify the LAC of the
ACCM negotiated with the PPP peer.
In practice, different LAC manufacturers implement different support for ACCM.
Therefore, an LNS needs to determine whether or not to include ACCM in a
message as required.
By default, an LNS sends control messages including ACCM. You can configure
the LNS not to include ACCM in a message if the LAC does not support ACCM.
Follow these steps to specify to include ACCM in control messages:
