Trying to route mDNS traffic as you describe is a recipe for pain. The easiest way I know to do this: 1. install avahi (should be in ports) and bind it to your internal interfaces 2. set enable-reflector=yes 3. go pour a tall glass of scotch mdnsd would no longer be needed as it doesn't do what you expect. avahi takes its place and enable-reflector=yes is a 'town crier' mode where it relays mDNS traffic between the vlans. mrouted is not needed either unless you have another purpose for it. of course make sure you can pass/accept mDNS traffic (udp 5353) in your pf rules. You will also need rules to pass traffic of the actual services advertised via mDNS e.g. Airplay between vlans of interest.
