With the NPE-200, the box will probably max out at 2000 sessions if
you aren't doing anything else. Latest 12.2T/12.2B code has
scalability enhancements to decrease memory and cpu load for BBA
sessions, so it should allow you to squeeze the most out of the box.

Thanks Dennis for your valuable advise.

From the following website,
http://www.cisco.com/en/US/products/hw/routers/ps314/prod_module_configuration_guide09186a008007c79b.html

it mentioned that "CAR policing algorithm impacts performance due to its
additional use of processor resource. Typical performance impact may be
about 20 to 30%, although it would vary depending on the traffic mix and
the configured protocol:"... "Using an ACL with CAR will affect performance
depending on the type of ACL used"

The above document is meant for Cisco 6400 series. Does it applies to Cisco
7206 router?

May I know how bad is the impact on the CPU resources if the CAR is
configured on the virtual template, compared to configuration done via AAA?

Thanks.

yes it does if you are not making use of the 7401 or the 7200 with NSE-1
which can perform services in PXF. if you are doing software forwarding,
there is a performance degradation with service enablement in a number
of cases.

i don't believe the method of provisioning has impact on actual performance
other then your Calls Per Second rate.
