Should this conversation not move to the int-area?

1. CPE configures a pre-PANA IP address using DHCP
2. CPE runs PANA
3. CPE configures "session IP address" using DHCP
The PANA idea if using short lease/long lease DHCP address switching in
DSL deployments is simply not feasible. BRAS's with over 60K
subscribers are common and many providers have central city pops of more
than a million subscribers.
During a pop restart the 60 second lease on a million subscribers would
at best result in a sustained load of more than 16000 DHCP requests /
second smashing through the relays and into the DHCP servers until the
users had gradually authenticated.
