Question

SD-WAN link selection based on link utilization

Hi,

I have below requirement

 

  • Have 2 WAN links
  • Need to steer the O365 destinated traffic by default from WAN1. If the WAN1 link was hit 90% percent of the bandwidth, need to be fail-over to WAN2. After the WAN1 utilization become fine need to fail-over again to WAN1.

Can we do this in SD-WAN?

Hi,

 

Yes I checked this. But Spillover is applied for the traffic that is not matched for any sd-wan rule.isn't it?. I need to steer only O365 related traffic not the all internet traffic.
