Scenario:
Trying to pull a raw MC stream. no upstream router
-The source is sending the MC stream. The port is incrementing MC packets but the source port isnt forwarding the packets to the reciever attached to a different port.
-IGMP snooping is enabled. But there appears to be a valid join request from the receiver
-The source is a raw MC stream...no upstream router
-running a VLAN - it's the RP/ Rendezvous Point...its running PIM spare mode
- IGMP snooping is on and working for many other MC streams
- terminated directly in the VLAN
-the Cisco 4948 looks like it knows our DCM wants the stream
