The router doesn't really need to support anything, the mDNS packets just flood the bridge domain directly between clients like any other flooded packet.

That’s the nice thing about mDNS. No flooding of anything since it’s multicast and not broadcast.

It would be nice... if it were actually "real" multicast :). It's instead link-local multicast, which has none of the filtering advantages of traditional IP multicast (i.e. no group joining via IGMP is performed for the switches/routers to be able learn who actually needs to listen) https://community.cisco.com/t5/switching/route-igmp-link-loc... https://community.cisco.com/t5/switching/multicast-on-the-la....
The advantage of link-local multicast over a plain broadcast is it gives a unique address (IP and multicast) so the clients themselves can more easily filter them. That's about it.
