What sort of GRE performance should I see from those? GRE is not supported on the small Catalyst switches. It does work (in some versions?) but only at low performance and with high CPU utilization... And, again, it's not supported. Yeah - I've since found that on the Cisco website. But, what about GRE performance on true routers?

But it won't verify the source address on GRE packets it receives, which makes it feasible to forge GRE packets without forging the source address, which in some configurations makes some attacks easier.
