I have four B250 M2 in one 5108, only one 6140 FI , uplink is a 3750G-24ts switch , All B250 install vmware Esxi5, have one redhat vm on each B250, i have a software use 234.0.100.32 multicast address communication each other , I enable multicast routing on 3750g , I can see multicast group on 3750G , but my software working very unstable. if i mirge all redhat vm on one b250 , the software work fine . how can i solve it ?

on the 3750 you can configure an igp querier so the multicast entries won't time out after 3 minutes

I use ip multicast-routing on 3750 already,
HXUCS-A(nxos)# show ip igmp snooping groups
Type: S - Static, D - Dynamic, R - Router port
Vlan Group Address Ver Type Port list
294 */* - R Eth1/5

Veth741
HXUCS-A(nxos)# show ip igmp snooping mrouter
G - G-pinned, Q - Query accepting interface
Vlan Router-port Type Uptime Expires

HXUCS-A(nxos)# show ip igmp snooping querier
