How do I do Bonjour friend networking with Cisco?

What do I need to know about Bonjour to make sure our Cisco network is Bonjour Compatible?

From what i've read about Bonjour starts the discovery process by using a UDP mDNS. But what do I really need to tell the Cisco tech to make sure the network ends up being friendly to Bonjour traffic. If I had to guess, i'm thinking multi casting and mDNS across subnets? Is there a white paper or some thing?
