Greetings -
I have a scenario where a customer has two campuses - main and branch. The main campus has a primary 4GB Internet connection via a non-Meraki firewall and a backup Internet connection using business cable modem with a Meraki MX used here. The branch campus has a 10GB, point-to-point dark fiber back to the main campus and its own business cable connection with a Meraki MX connected to it. There is a 'backup' connection using a site-to-site VPN between the two sites using the cable connections and Meraki MX appliances. (see diagram).
The customer uses multicast traffic to send audio broadcasts from the main campus to the branch campus. This works fine until the 10GB fiber connection goes offline. Normal IP traffic works but we cannot get multicast traffic across the VPN connection using the Meraki MX appliances.
Is multicast traffic across a Meraki MX site-to-site VPN connection supported? If not could I use a GRE tunnel across the site-to-site VPN?
Any information/input is greatly appreciated.
Cheers
Joe
