What is the Viptela behavior of AAR when a single tunnel is degraded and how does this behavior change with routing?
Am I correct in understanding that you choose to use specific routes (no SLA) OR you choose to advertise the same routes from each datacenter and utilize SLA classes to move traffic to a different color?
From: https://sdwan-docs.cisco.com/Product_Documentation/Software_Features/Release_18.1/07Policy_Applications/01Application-Aware_Routing
"You cannot direct traffic to tunnels based on SLA classes."
In an example, consisting of a branch and two datacenters, each using private1 and biz-internet transports. RTP traffic is defined in a SLA class that prefers color private1.
What happens to RTP traffic when a branch bfd probes determine there is too much latency/loss for SLA class to datacenter 1 only?
1. Assuming routes are ECMP, would it attempt to send traffic to DC2 over private1?
Or does SLA force a failover to biz-internet and ECMP - Ignoring the valid private1 path from Branch to DC2?
2. How does this change if routes advertised are more specific out of DC1 for this RTP flow?
If there are specific routes advertised from DC1 would it completely stop using private1 color and instead use a remaining color to get to DC1?
