Multicast through Point to Point Bridge

[Edgar Khachatrian]

Hello,

I have a Pint to Point bridge set-up with two cisco AP's, and I am having trouble passing multicast/broadcast traffic through it.

Any one any suggestions?

Thanks

[Stephen Rodriguez]

can you post the configs of the devices?

What are your phy rates set at ? Multicast is sent over the highest mandatory rate. If your bridge phy is lower than mandatory rate multicast would not tx ..

Am I off base on my comment Steve ?

[Stephen Rodriguez]

aIOS uses the lowest configured mandatory rate, WLC uses the highest configured to send multicast.

If you have the 'base' config 1M would be a mandatory rate IIRC and multicast should flow.

of course if you are going across L3 boundaries, you need to make sure you PIM enable the L3 interfaces

+5 Steve .. thanks for the correction. I was thinking that was the case, glad you could confirm..

The AP's are barely 25 feet apart with good line of sight. So I doubt that the the mandatory rate is the problem.

However I will try this as the last option.

Thank you

Try this, let's disable the port-protected under the radio interfaces.

Hello Ed,

As per your query i can suggest you the following solution-

To set a Point-2-Point bridge with two AP's and passing multicast/broadcast traffic throuh it yo can use WLC with highest configured multicast send rate.Also make sure that you have enabled PIM as you are going to communicate through layer 3 network. Use an IOS with lowest configured mandatory rate.

Hope this will help you.

[Edgar Khachatrian]

I don't use a WLC, however I have been looking for the command to configure the multicast rate per second..

Can anyone show me the command for this?

Also how do I enable PIM on a Autonomous AP?

Lastly I will try lowering the mandatory rate.

[Stephen Rodriguez · Accepted solution]

AP's are layer two devices, PIM is enabled at L3.

HTH,
Steve

OK. So I dont need PIM.

What is the command the command to increase the multicast rate per second??

Edit: Ok... So I had tried "no igmp port snooping", on the radio interfaced... However I had to do it on the trunked switchport....

Works now....

Thanks to everyone.

Really appreciate all you help.
