in this case you can ensure that the same user will get the same IP
address regardless of where they connect to the access network via the use
of either L2F or L2TP tunnels. rather than using multiple radius server
deploy radius proxies which backend to a central user radius database.

Hi,

A Service Provider, having several POPs, I presume
will be using at least one RADIUS server that is
associated to each POP, and are usually colocated
at the POP, along with the RAS, aggregation and other
IP service devices.

And the IP address assigned for a subscriber dialing
up from one location is assigned by the corresponding
RADIUS server, after authentication. If this is the
case, how is this subscriber provided service like
internet connectivity, when he travels to another
part of US? Will the RADIUS server info be available
to all the POPs of the Service Provider? How are
the current ISPs doing this?

To take it further, when policies are associated with
this subscriber that are based on IP address, how
is that handled when the subscriber travels?

Your input on this will be greatly appreciated.

thanks.
Mohan
