Hi
I have a lab below:
pc1(source 224.0.127.1)--------(port4 vlan 3)
pc2(receiver 224.0.127.1)--------(port6 vlan 6)
pc3(receiver 224.0.127.1)--------(port8 vlan 3)
and all PC1 PC2 PC3 are connected to 3550
The problem is when I enable MVR. PC2 can receive multicast, but PC3 can't
not. Can someone give me some config example or hint to solve the problem. I
think PC2 and PC3 both can receive multicast when MVR is enabled. Am I
right?
######When I jon the group on PC 3 I get the below debug log##########
Oct 4 22:46:33: IGMPSN: group: MVR takes pkt in Vlan 3
