[c-nsp] CPU load on 7206 with 1200 DSL users

[Antonio Querubin]

We're considering moving approximately 1200 DSL and a handful of Frame 
Relay users provisioned over 2 DS3s on an aging Redback SMS-500 onto 
another router.  One of the devices under consideration is a Cisco 7206 
VXR using ATM RBE for the DSL provisioning.  The 7206 VXR currently has a 
NPE-300 which we might need to upgrade if we use it for this purpose.

I'm interested in the CPU average and peak loads I can expect with 
approximately that number of users in that configuration or with other 
still-supported NPEs.  We also poll all our devices every 5 minutes via 
SNMP for bandwidth usage data so that can drive the CPU load up a notch. 
Each end-site would be provisioned on a separate subnet/interface with 
uRPF enabled.
