Help with 7200, PPPoE, Virtual Templates, and PVCs
We are a telco and ISP offering DSL service to our customers, and currently have an OC-3 link from our Cisco 7200 to our ATM switch that aggregates the traffic. We currently have a vpdn group set up to accept the incoming connections, but I have some concerns about limitations and am looking for some advice (router info at the bottom). I thank you in advance for any help you can provide.
1. Is there a limit to the number of Virtual Access Interfaces that can be created on the 7200? When I do a 'clear vi ?', it shows the session number from 1-101, so I am very concerned. If it can support more than 101, do I need to create new vpdn groups? If not, is there another way I can terminate the sessions (i.e. not Virtual Access)?
2. Is there a limit to the number of pvcs that can have simultaneous connections on the 7200? I know the theoretical number is around 4000, but is there a more practical number when you begin seeing performance degradation?

The maximum number of PVC's is 4096 depending on the actual interface card installed. http://www.cisco.com/warp/public/121/maxvp_vc_3.html. There is no way to give a more practical number for degredation as it would depend on the amount of traffic going over these PVCs.
