I have been playing with Meraki SD-WAN policies to sort out some of the VOIP issues that we face from time to time.
I have a quick question, Under SD-WAN and Traffic shaping settings if we have WAN 1 as the primary uplink with load balancing disabled (in global preference) and we were to add a VPN traffic preference under SD-WAN policies to send our SIP traffic via VPN over WAN2 provided that it meets VOIP performance class would that override the global preference of primary uplink WAN1 and SIP traffic would flow over WAN2? Our local Etisalat carrier is much better for voice traffic but we have limited bandwidth from them hence WAN2.
I am following this KB - https://documentation.meraki.com/MX/Firewall_and_Traffic_Shaping/MX_Load_Balancing_and_Flow_Preferen...
The reason for asking this question is that I have run captures on the secondary WAN and it appears that the traffic is still going over the WAN1. There is no local breakout at the site, All traffic must go to the remote hub for break out to the internet which is an MX450 appliance in our DC.
I also have a subsequent question, are the VPN traffic preferences executed in the order from top to bottom? Similar to firewall rules?
