Traffic Flow Preferences and fail-over

Not sure if anyone can answer this but on an MX xx

 

If I have 1 ISP on WAN1 and second ISP on WAN2

 

I have a flow preference that sends the traffic for 192.168.50.0/24 through WAN2 so the rest of the network traffic will route via WAN1.

 

What happens if I lose connectivity to WAN1, will all the network traffic now route through WAN2 as the failover ?

 

Any thoughts would be appreciated.

 

Thanks

 

Gary

Correct, if WAN1 fails all traffic will now flow out WAN2.

Having an issue with 4 minute failover for my WAN 2 on MX100. Call support . They tell me it can take up to 5 minutes. failover kicks in at 2 minutes which is tooooo long

If you have an interface simply go down it is quite quick.  But if the interface remains up because you have an upstream failure it can take a while.

Called into support last night..... they were able to change the timeout to 30 seconds on WAN2 on my primary and secondary MX. SOOOOO HAPPY! New backend feature.
