I have a L3 switched LAN (Cat4510 at the core with 3560 to the edge), and a WLC 4402 [s/w 22.214.171.124] providing wireless access. There is a multitude a PC's and MACs that sit on the wired and wireless network.
I currently am having issues getting a Apple tool called Bonjour working across the wireless network.
I have done some reading and from what I can gather it uses mdns (which uses udp 5353 / 5354). I have enabled Multicast Routing on the Cat4510 and enabled on the WLC 4402 Ethernet Multicast Mode with a group address of 126.96.36.199, however still cannot get Bonjour clients talking.
Admittedly the blogs I have read and Tech pages on Apple do not give up anymore info than this. Has anyone had experience or come across this before?
