Tunnel Setup Autentication

[S Ramakrishnan]

My question pertains to setup of layer 2 tunnels (especially L2TP tunnels). I understand
that after a tunnel has been setup,
a user may dialin to a LAC and be authenticated 
by the LAC and/or the LNS using RADIUS
or other means and creation a new session
on that tunnel.

What about tunnel setup itself?
What kind of authentication
is performed during tunnel setup?

Any info greatly appreciated.

Thanks !

Rk
