BR1 SFVPN learned routes limit

Hi,

Just wondering if anyone has any experience of any limits (physical or imposed) on the number of routes a BR1 can learn.
We have a project where we are going to be using a BGP peering between a cisco router and a balance 1350 where the 1350 will be learning ~2000 routes. It will then be exporting the learned routes to OSPF and as such will be sending them to all the edge connected devices over speedfusion. Therefore we will have BR1 learning >2000 prefixes and we are wondering if anyone has any experience of doing this and if they have seen any issues from doing so?

Thanks
James
