Usage guidelines
Tunnel authentication prevents the local end f rom establishing L2TP tunnels with illegal remote
ends.
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.
For tunnel security, enable tunnel authentication.
Examples
# Enable L2TP tunnel authentication.
