Bidirectional Forwarding Detection

In this video, Charles looks at the topic of Bidirectional Forwarding Detection (BFD). BFD is a lightweight UDP-based protocol used for fast forwarding path failure detection. He discusses the advantages of BFD over traditional protocol timers, and looks at a configuration example with OSPF.

That was brilliant! I had prepared myself to watch 3-4 videos to get BFD concept but I guess I won’t need it after this 🙂
Thanks for excellent and thorough explanation!!

you guys videos are the best explained + configuration. I paid for your ENARSI(300-410) complete video course and so far its been great! I have CML 2 so being able to upload the labs and trouble shoot is a plus. Great Work!!!

[@blendonator]

Okay, that is super cool! I never knew that existed, thanks!

[@intent7705]

Thank you! With having an interface listed as a passive interface, would you still need to additionally configure "ip ospf bfd disable"?

[@tigisteshetu5932]

The best explanation 👌 keep it up!!!

[@azatkhan4714]

Thank you for your time it was super!!

[@rafaelguedes1000]

Fantastic!!! I understand we can lower dead timer and get quicker, but how quicker is that? Thanks in advance!

[@TheSankywanky]

Super explanation. I have a question, does the bfd timers (e.g. 50msec) should be same on both the neighbors? (R1 & R2 in this case?). OR R1 can have 50ms and R2 can have 70ms?

[@nadzeyahutsko1094]

Hello sir, As per you BFD is configurable in all Routing Protocol. In static routes, is it possible ?

[@post-man23]

Hi, what’s the difference of enabling it on the interface and enabling it only under ospf? Thanks in advance.
