reduce failover times MX SD-WAN

[LeoAri]

Hello friends
I have two MXs running as active passive and I have two internet links WAN1 and WAN2, when WAN1 does not reach 8.8.8.8 it switches the traffic from WAN1 to WAN2, it is correct. But the time is very high, approximately 30s, in "uplink selection" the "wan failover and failback behavior" is in "Graceful", I think to change it to "immediate" but I don't know if that helps.
Is there any way to reduce the failover time?

Hi ,

Are you trying to fix something ?

Is it the fallback or the failover timer you are trying to fiddle with ?

Hi

The configuration works, that is, it switches from the WAN1 link to the WAN2 link, but the times are very high, more than 30 seconds. I would like to know if there is a way to reduce the failover time.

You can't change the timers before it marks the wan port as down.

But For sdwan traffic you are able to set policies.

This can also be done for local breakout traffic but then you need sdwan+ license
