Hi all,
Is it possible to multicast from one public vlan to another?
Setup is:
!
ip multicast-routing
no ip igmp snooping
!
interface Vlan1
description multicast are running here
ip address 1.1.1.x.x.255.0
ip pim sparse-mode
ip igmp static-group 233.62.223.2
ip igmp version 3
ip igmp snooping fast-leave
end
!
interface Vlan2
description I want to watch my multicast stream ***
ip address 2.2.2.x.x.255.0
ip igmp join-group 233.62.223.2
ip igmp version 3
end
!
When i have an ip adress in vlan 1 I can connect fine to the multicast stream - but when I'm in vlan2 I cannot connect.
Regards,
Philip

Hi Philip,
So you have multicast server on vlan 1 and you want to receive multicast traffic on vlan 2 correct?
Can you also configure "pim" under interface vlan 2 and see if that works?
Also can you paste the output of "sh ip mroute" once you configure pim under vlan 2?

Also make sure the multicast source application generates the multicast stream with a TTL of at lease 2. Otherwise, the router will simply drop the packets.
Hope this helps,

Hi,
I too am having the exact problem. I have added PIM and join group (as per the application), but the vlans fail to see M/cast traffic between them.
Can anyone post some configs that will allow multicasting to work between separate vlans on a 6509 IOS device?
