Configuring L2TP tunnel authentication
You can enable tunnel authentication to allow the LAC and LNS to authenticate each other. Either the LAC or the LNS can initiate a tunnel authentication request. To implement tunnel authentication, enable tunnel authentication on both the LAC and LNS, and configure the same non-null key on them.
To ensure tunnel security, enable tunnel authentication.
To change the tunnel authentication key, do so after tearing down the tunnel. Otherwise, your change does not take effect.
