Loading ...From the Mikrotik WIKI:
Bidirectional Forwarding Detection (BFD) is a protocol intended to detect faults in the bidirectional path between two forwarding engines, including physical interfaces, sub-interfaces, data link(s), and to the extent possible the forwarding engines themselves, with potentially very low latency. It operates independently of media, data protocols, and routing protocols.
BFD is basically a hello protocol for checking bidirectional neighbor reachability. It provides sub-second link failure detection support. BFD is not routing protocol specific, unlike protocol hello timers or such.
What does this mean? It is a way to detect a failure between two routers that does not depend on the routing protocols they speak. For example, you can run BFD “on top of” OSPF, BGP, etc.
Some Caveats:
-Requires Router OS 4.4
-Does not support echo or authentication. If you are talking to a Cisco device you need to disable echo on the interface the Cisco uses to talk to the Mikrotik.
