In order to configure multicast-multicast mode on a WLC, I specify Multicast enabled and set a private LWAPP multicast IP under the General tab.
I have a different multicast IP set for Mobility Messaging.
If I have two or more WLC controllers, do these LWAPP multicast mode IPs have to be different or should they be the same between controllers, say on a WISM? I guess I need a better understanding on how this LWAPP multicast IP address is used exactly, for example, if a client is a receiver for some other multicast feed, what relation does this LWAPP multicast IP have?
When you use controllers that run version 4.1 or earlier, you can use the same multicast address on all the controllers. If you use controllers that run version 4.2 or later, the LWAPP multicast group configured on the controllers must be different for each controller used on the network.
