Configuring optional L2TP parameters

The optional L2TP parameter configuration tasks apply to both LACs and LNSs.

Configuring L2TP tunnel authentication

Tunnel authentication allows the LAC and LNS to authenticate each other. Either the LAC or the LNS
can initiate a tunnel authentication request.
You can enable tunnel authentication on both sides or either side.
To ensure a successful tunnel establishment when tunnel authentication is enabled on both sides or
either side, set the same non-null key on the LAC and the LNS. To set the tunnel authentication key,
use the tunnel password command.
When neither side is enabled with tunnel authentication, the key settings of the LAC and the LNS do
not affect the tunnel establishment.
