Monitoring reachability ASA

[aehtibarov]

Hello Friends,

I have two link to partner company, one primary and one backup.

I wanna track reachability over primary link so if this goes down I add route over backup link. 

Normally i do it with ip SLA.

However i want when primary link comes back to check it for 30 min if there is packet loss, if no packet loss for 30 min i want to go back to primary link. 
How can i do it on ASA or on Router?

ASA  and Router both should be same for IP SLA.

ASA follows below Guide :

you can use delay for failover back as per the requirement.

Thank you for respond . How can I use delay on failback ?

I was suggesting only on IP SLA Tracking side. example : ( so test before you apply in real production).  - most use case will not be that long, think other side, if the ISP 1 come up and you looking to fail over back 30min, what if ISP2 go down ? - so think before taking this hit.

If you specify, for example, delay up 10 down 30, then if the object state changes from down to up, clients tracking that object are notified after 10 seconds. If the object state changes from up to down, then clients tracking that object are notified after 30 seconds.
