Is there a way to set up a pair of MikroTik radios in a "dumb" bridge mode such that ZERO MAC table exists in either device, and instead ANY and ALL packets received on the ethernet interface are ALWAYS forwarded out the wireless point-to-point link? (No spanning tree, no mac table, no "learning" at all, instantly in forward-everything mode.) The only exception would be packets with a destination MAC of the device itself.
I know of other manufacturers of P2P radio links that have this mode.
If I have two switches at either end of the P2P link handle all the RSTP (doing Cisco-style per-vlan rapid spanning tree) and my P2P bridge devices will transparently pass ALL traffic (including BPDU frames between the Cisco switches), then I can set up P2P redundant links and let Cisco's Per-VLAN RSTP handle fail-over (and even do some load balancing by preferring VLAN X over link A and VLAN Y over link B until there's a link problem).
When the bridge devices are in "smart" bridge mode and "learn" device MACS, then there's always a chance that they'll learn and remember a MAC via the wrong direction (depending on where spanning tree is choosing to block a particular VLAN), which means if there's a link failure, it takes longer for the bridge devices to "re-learn" the new topology of the network and forward correctly. A dumb non-learning bridge is faster and always forwards and makes fail-over super fast in this particular case.
Now if RouterOS was Cisco per-vlan RSTP compatible, perhaps there would be an alternative...
