Guest Network Broadcast Traffic

We noticed this morning that our guest DMZ master controller is continuously sending a large amount of data to sites with local controllers that have no guest users connected to them. I am sure that this has been going on since we deployed the solution, but it has not presented itself as a problem until recently. We suspect that this is broadcast traffic and we would like to block it from being sent out from the guest DMZ master controller to our local controllers over the GRE tunnels. Is anyone aware of a best practice recommendation for blocking all broadcast traffic from the guest master to the guest local controllers?

Todd - Have a look at the broadcast-multicast optimization feature. I think that'll do what you want. It didn't come in until 3.4.2.5 though.

Todd,

This feature was turned on in 3.4.2.5 per Mike Gallagher's comments.

We are running 3.3.1.29 and 3.4.2.4 currently. Any suggestions for versions prior to 3.4.2.5? If not, we will look to upgrade.
