[MSM4310/VSM4320C] How to routing the mDNS packet between different VLAN.
Hi everyone
I try to setup MSM4310 and VSM4320C with multiple VLAN for divide control, video signal and so on.
On the other hand, I would like to enable the mDNS communication between the VLAN for device discovery.
However, even if I enabled IGMP settings, I only able to see the mDNS packet on the same VLAN.
Does anyone know how to routing the mDNS packet between the multiple VLAN?
Hi, the packets won’t naturally cross VLANs. To allow devices on different VLANs to discover each other, you need an mDNS reflector or gateway—either a feature built into your managed switch (sometimes called “mDNS Gateway” or Bonjour Gateway) or a small server running software like Avahi configured to forward mDNS between VLANs. IGMP alone won’t help because it’s meant for managing multicast traffic within a VLAN, not for linking separate VLANs, so using a reflector or proxy is the way to make mDNS work across multiple VLANs.

Thank you for your replies.
I will try to adapt the Gateway such as RP60X for managing the mDNA across the VLAN.
