Pascal, Did you measure and could share the recovery time you got using 250ms on BFD timers?

The bug id status is 'terminated/closed", however it doesnt seem to be fixed. Pretty funny that you sent this today, we were just testing SXF/SRB BFD compatibility. So far, the only workaround we have found is to set the BDF timers to 250ms. We're running 250ms BFD on SXF since over a year without any issue. As far as I remember 150ms was flapping, 200ms not, so we took 250ms to have some margin. If this doesnt meet your requirements, I urge you to ask cisco to reopen this Bug since its absolutly not fixed.
