Cisco Bonjour Gateway Solution in Release 7.4
Bonjour is Apple’s version of Zeroconf – mDNS with DNS-SD. Apple devices will advertise their 
services via IPv4 and IPv6 simultaneously (IPv6 link local and Globally Unique). Current 7.4 
implementation does not support Bonjour Snooping for IPv6 addresses. On an iPad, IPv6 cannot be 
turned off and no change can be made to any of the Bonjour settings.
If you want to control mDNS/Bonjour, the key is to limit the size of the local segment. 
To address this issue Cisco WLC acts as a Bonjour Gateway. The WLC listens for Bonjour services and 
by caching those Bonjour advertisements (AirPlay, AirPrint etc.) from the source/host e.g. AppleTV, 
responds back to Bonjour clients when a request for service is initiated. The following illustrates this 
process.
1.
The Controller listens for the bonjour services
2.
The WLC then cache those bonjour services
3.
Listens for the client queries for services
