Hello,
Not sure what exactly You are trying to achieve, looks like You want to
delay announcing this link into OSPF (and by extension, using it for
transit traffic) unless it has been stable for 3 secs.
You could achieve this by defaulting this link to broadcast (if it is
currently configured as"interface-type p2p") - there is a Waiting state
equal to Dead timer once the OSPF interface comes up. And it interface
flaps during this time, Waiting timer starts again.

Thanks

Dear experts,
I currently have a wan link between two MXs that sometimes is experiencing
errors.
I’ve on top of the link OSPF (timer 1/3) as routing protocol and I’d like
to find out any possible way to exclude the link when errors are in place
and below to the 3 seconds of the OSPF timers.
I’ve analyzed the following:
1) BFD with OSPF but it doesn’t support hold-time (as BGP does), in
order to avoid OSPF flapping and generate higher instability I cannot use it
2) RPM event based script: probe interval is currently not below of 1
second, hence to detect results with no false positive I need some sampling
and we’re still at 3 seconds or more
Any other possible options ?
OAM ? does it support hold-time ?
Cheers
James
