VRF Aware IPSEC Tunnels

Hi Folks,

     I am looking for a way to consolidate multiple VPN routers in to a single endpoint.  From what I can tell the max VPN tunnels on a 3945E is 3000, but since these are customer tunnnels with overlapping address space I need to create VRF Aware IPSEC tunnels.  I came accross the article below that indicates 75 VRFs are recommended on a 3945E.  However this article references MPLS switching.   Are there similar numbers if we are just doing VRF-Lite?

Thanks,

VRF Aware IPSEC Tunnels

if you have just one public interface you can't have serveral vrfs on one interface. The article explains a regular MP-BGP

if you are the customer and you can connect to your ISP on a trunk link using different logical interfaces yes you can have one vrf on each interface and the ISP will route your vrfs through his BGP core

cheers
