Is BFD (Bidirectional Forwarding Detection) supported in any of the ASA Versions ?

can u please let me know how it is accomplished via ACL.Can you please look at the below URL and confirm whether this feature is really supported on asa ?

Just to clarify. Do you mean can the ASA participate in BFD ie. does it support it ? In which case as far as i know no it doesn't.
If you mean can BFD be used throgh a firewall then yes you should be able to do this. You would need to allow the BFD ports -
bfd-control Port 3784 TCP BFD Control Protocol
bfd-control Port 3784 UDP BFD Control Protocol
# [RFC-ietf-bfd-v4v6-1hop-10.txt]
bfd-echo Port 3785 TCP BFD Echo Protocol
bfd-echo Port 3785 UDP BFD Echo Protocol
# [RFC-ietf-bfd-v4v6-1hop-10.txt]

I believe BFD works over IP, so opening ACLs should do the trick.
There is no inspection on the ASA for it, that is for sure, but I don't think one will be needed.
I haven't tested, so not 100% sure.

Hi Experts
BFD is not working in ASA 9.9 running on FPR 9300. Maybe limited or no support?
Tried both single/multi hop BFD template and map.

Hi, I have bit effort to answer your question.
BFD (Bidirectional Forwarding Detection) is a super fast protocol that is able to detect link failures within milliseconds or even microseconds.. All (routing) protocols have some sort of mechanism to detect link failures. For more detail see https://community.cisco.com/t5/network-security/query-regarding-bfd/td-p/1493452-apkbik
Thanks
