Re: BFD

have you checked your physical connection ? because BFD get failures faster , may be you have up & down in your physical connection.
if the points i have mentioned does not worked , another question i have is your router connect directly or there is another router/switch in the path ?

Re: BFD

Hi,

Is BFD enabled on this interface? If yes, you may want to remove it and test again or check to make sure that both sides of the connection match.

Re: BFD

Hi Team,

 

As per cisco document because of this accelerated handling of BFD control packets, all output features are bypassed. Users cannot, for example, filter or apply Quality of Service (QoS) to transmitted BFD packets.

 

Is there any posibility to filter or apply Quality of Service (QoS) to received BFD packets.

 

Kindly help me to know the same if possible share cisco doc as well
