Tim,
   I am assuming you are using a Cat5500 and have set the vtp domain, set
the trunking and added the vlans you want it to trunk and so forth, if so,
did you make any modifications to the broadcast parameters on the switch? I
recall reading somewhere that you need to set the broadcast on the port to
0% but if you do this, your neighbors will never form. If you had neighbors
prior to modifying the broadcast, they will be there till you reboot. Did
you "set cgmp enable" on the switch? Did you use the command "set ip
multicast router mod/port" on the switch port that is running multicast
routing?
