I'm having trouble getting Multicast Traffic to work. We are attempting to enable Multicast Routing so that our workstations receive paging in the event of an emergency, and we are using MS250's at our Test Site. Configuration is as follows:     The Multicast Originator is directly connected to SW02, therefore we configured the Multicast Interfaces on this switch.   When we do a test page to a workstation on a VLAN other than the multicast originator's VLAN, they will receive a Notification Box, which means that they are getting the notification, but no audio is heard.   When the workstation is placed on the same VLAN as the multicast originator's VLAN, they receive the Notification Box, and the audio is heard.   My hunch is that I may have misconfigured the RP for this multicast stream, but I am uncertain if that is the issue.   Any tips or assistance with this issue would be greatly appreciated. Thanks in advance!  ... View more
