Multicasting help

Posted previously under switching. Previous post deleted. Can anyone offer advice?

 

We have been trying to get multicasting to work without success for over a year. We would like to use it for Microsoft SCCM. We have used 2007 and are currently using 2012.

 

So his is our setup.

 

Core switch - From vlan 12, a station will use multicasting correctly, from vlan 18, it fails.

vlan 12 - servers (SCCM Server)

vlan 18 - workstations

ip multicast-routing

vlan 12 - ip pm-dense, ip igmp

vlan 18 - ip pm-dense, ip igmp

 

We also have 5 secondary switches that are trunked to core.

They simply have 

vlan 12 - ip igmp

vlan 18 - ip igmp

 

Lastly, there is a management vlan (11) that the switch lives in.

 

Any idea what we are missing? It seems to be a routing piece since we cannot multicast across vlans. I am also unclear on how to configure the querier.

Was it your old topic from last year:

No, but I will mark both as resolved.

 

When enabling PIM routing, you apparently MUST reboot the switch. I can't find this in the documentation, but this solved our problem. Since this was on our core switch, it had not been rebooted in about 500 days.

Hi There,

 

Have you try to  use  Sparse Mode instead of DM??

 

Also create the rendezvous point of your multicast environment
