We have an issue in our environment where branch locations in our SD-WAN topology will have partial connectivity after state changes in our network. For example, we recently had to failover to a secondary firewall and a large # of branches lost communication with our network monitoring server. We could still SSH into some of them but not into others. Since all traffic is backhauled to our data center, this may change routing interfaces causing connections to reset. This behavior also occurs when the ISP goes down on our biz-internet circuit causing a similar connection change. Has anyone experienced this in their environment? Please let me know if you need more details.
