LACP Bond, Switches and Bridging

RouterOS General
1

I’ve got a weird problem I hope someone can help me with. I’m trying to create a LACP 2-port bond between an RB1100AH and a Netgear GS716Tv2. Everything works ok until I add the bond into a bridge. At that point, the Netgear sees the bond as down and stops load-balancing/failover.

I’ve experimented with all sorts of bridge filter rules, including not having any at all, and I’m stumped. If I route to the bond instead, it stays up just fine.

Right, so LACP uses multicast for the LACPDU packets, so do bridges not pass multicast traffic by default, perhaps? If there are no filter rules configured, should a bridge pass all traffic or no traffic?
