I'm a Consultant for several large education customers who are moving to VLAN enviroments and now need to route this traffic. Have you found a solution or a way to force the routing through a Cisco L3 Device? Thanks, Josh Just read this post concerning your problems routing Bonjour traffic between VLANs.

Your biggest problem is that it's the TTL of multicast packets, mDNS by spec should have a very low TTL. I can't say about Cisco L3 devices, we don't have any, we're Juniper, Extreme and Foundry for routing. We're phasing most of our Cisco switches out, mainly because the Cat 3550's do "strange" things with multicast. We'll probably end up with few dozen 2950's.
