Okay, so you want all trunk ports, that make sense.
I still recommend using bridge vlan-filtering=yes. Your issue with that is the BRIDGE-LAN itself needs to be in the tagged= list.
/interface bridge vlan add bridge=BRIDGE-LAN disabled=yes tagged=BRIDGE-LAN,sfp-sfpplus2-LAN vlan-ids=2,5-7,10,12,16-39,101-800,3000
_@sindy has an article that describes the WHY tagged=bridge,… is needed, http://forum.mikrotik.com/t/routeros-bridge-mysteries-explained/147832/1
Also, I’m not sure what you’re doing with horizon= on most of the ports. And with split horizons everything gets more complex, see https://help.mikrotik.com/docs/display/ROS/Layer2+misconfiguration#Layer2misconfiguration-Bridgesplit-horizonusage.
Also noticed you have sync-connection=yes enabled. While not sure what effect it have on DHCP if VRRP isn’t failing over… Might disabled that to see if it has an effect.
