Default [Snort-users] Snort on two load-balanced links (using SPAN on a Cisco 6500)

I am considering using Snort to monitor two uplinks on a Cisco 6500 into
the core. This will be done using SPAN to mirror the traffic on both
uplinks to single port. Assume that bandwidth is not a problem.

These are equal-cost routes, so traffic will be load-balanced by OSPF.
(I think this is load-balanced by flow, not per packet).

Does anyone know what the effect this setup (load-balanced links) will
have on the ability of Snort to do it's job?
