BFD session status notification

[Winston Chen]

Hi,


I am wondering if there is a way an application can be notified when BFD 
session status changes.

I know currently I can check the BFD session by polling with birdc or 
scanning the log, but if there is some way I get the notification it 
would help me much more.

The reason I am ask this is because when I used keepalived, I found 
keepalived can send VIP events to an FIFO and my application can get 
these events from it.


Thanks.

Chen
