Re: Cisco 7301 as LTS With Hundreds of Domains

The ISP I work for uses "authenticate before
forward" for some private VPN
services we offer.

Essentially your LTS/LACs will authenticate the user, and
the RADIUS
response contains details about where the session should be
forwarded
(rather than what details to terminate the session with),
which can be a
list of your LNSs which the LAC can load balance accross.

Once the session has been forwarded on, your LNSs will
authenticate the
user, and terminate the session.

I believe we are using two RADIUS instances for this, one
for the auth
before forward stuff, and the second to actually
authenticate the users
for termination on the destination LNS.
