‘Loop Protect’ – New feature in 6.37rc24
Long-time MikroTik users have been after better loop prevention mechanisms for quite a while now. Rapid STP within bridges was the only feature available up until Fall of 2016 and now MikroTik has released Rapid Spanning Tree in hardware for switched ports as well as a new Loop Protect feature that seems to serve the same function as Cisco’s Loop Guard but not utilize spanning tree to detect the loop. MikroTik’s version compares the source MAC of the loop protect frame with the MAC of the interface it is received on and if they match, it will disable the port until the timer expires and check again for the existence of a loop.
This feature was introduced in 6.37rc24 on August 31st, 2016.

Use cases for ‘Loop Protect’
Loop protect seems to be designed more as an edge port protocol since it physically disables the port upon detection of a loop, whereas STP will leave the port physically active but logically block traffic on that path. Some potential use cases for enabling this feature could include:
