I’ve had to run OSPF on a bridge in a pinch, and so long as you don’t make any live changes to the bridge (adding/removing interfaces), the Mikrotik won’t mind. Just remember to set your static OSPF interfaces (if you have any) accordingly. Same goes for MPLS – LDP Interfaces if you’re using it. If you’re thinking it’ll be like this for longer than a week, leave yourself plenty of documentation to backtrack properly. Nothing like coming back to it three months later and trying to remember what you did!

SAF has a gigabit port, but it only offers the option to lock it to 100, not gigabit. so I have the mikrotiks set, just not the otherside, the port still flaps on both radios what was happening is everytime it flaps, the interface dropped in ospf and went neighbor down, rerouting traffic then coming back up what I did was made a bridge, added that port to it, and put the ospf ip on the bridge itself, this allows the port to flap without the ospf interface going down until we work throught the issue with SAF I'm wondering if this is causing some other harm having it on the bridge, rather than the physical port
