MPLS VPN support

[agreenwald]

I have a customer who would like to know how many

VPNS or vrfs can be supported on a 7200/7500/GSR?

They would to scale these platforms and are trying to understand the limitations for growth.

I think I remember my Cisco rep saying the 7200 supports up to 2000 full duplex DES or 3DES tunnels at 90 mbps with the optional encryption acceleration adapter. I would guess maybe 500-700 maximum without the adapter. You obviously need to take into consideration the traffic, memory consumption, CPU utilization, features enabled, etc.

Hope this helps
