multicast routing on 3750 switch

Hi Experts,

I'm trying to lab out very simple scenario using IE LAB workbook 1 Ver 5,
task 8.3

Sparse-mode.

R4<---->R5 (RP) <---> SW2 <---->SW4

SW4
interface Vlan10
 ip address 155.1.10.10 255.255.255.0
 ip pim sparse-mode
 ip igmp join-group 224.1.2.3

when I tried to ping 224.1.2.3 from R5 SW4 never replied. SW4 is 3750, when
I replaced it with 3550 or 3560 everything was perfect.

Is there any caveat here or I'm missing something?

Thanks in advance,
ZZ
