Multicast Forwarding IGMP Pruning

[Googer]

I have a Procurve 5406 and I'm trying to propagate a multicast to all the vlans. I have pim-sparse running on all the subnets. I do get the multicast to forwared but occasionally it will get pruned to one of the vlans. I am trying to set it up so that this multicast will allways be forwarded to my target VLANs. I used the ip igmp forward command on the port where the multicast originates but this did not work. This multicast is a time update to our IP phones and when it goes down they don't reconnect to their time updates until I get the multicast forwarding their vlan again. Config is as follows.

router pim
bsr-candidate
bsr-candidate source-ip-vlan 1
bsr-candidate priority 1
rp-candidate
rp-candidate source-ip-vlan 1
rp-candidate group-prefix 224.0.0.0 240.0.0.0
rp-candidate hold-time 150
exit

vlan 1 (Multicast Source VLAN)
name "DEFAULT_VLAN"
untagged A3-A24
ip address 10.10.10.1 255.255.0.0
ip igmp high-priority-forward
ip igmp forward C1
exit


vlan 102 (Destination VLAN)
name "Client VLAN"
untagged A2,A7,B2
ip address 10.20.10.1 255.255.0.0
ip igmp high-priority-forward
exit


Any help would be appreciated.
