I have two bridges, "101" and "102", with VRRP beween two routers "r1" and "r2". By default 101 is priority on r1, 102 is priority on r2
Routing between the two is all fine, but MDNS on vlan 101 obviously doesn't get added to vlan 102, and vice versa.
If I set up mdns-repeat-ifaces on r1 with bridge101 and bridge102, that copies the messages just fine.
If I set it up on r2 though I get a loop, an MDNS message comes from a device on bridge101, then is copied by r1 onto bridge102 (fine), but then r2 sees this message and copies it into bridge101, which r1 sees and again copies it
(And of course it also happens the other way round wirh r2 copying the first message)
My current thinking is a firewall rule on the input chain to block MDNS from the IP of the other router, or am I missing something else?
