I have a question for the respected forum.
The SD-WAN production environment is usually comprised of more than one SD-WAN controller/manager. Different SD-WAN sites might reside under different controllers/managers. So my questions related to the given scenario are:
1). What would be Cisco Viptela’s approach for management and orchestration in order to establish an overlay connectivity between the sites which are managed by different instances of controllers/managers?
2). In case of failure - Is there a fail-over mechanism to reroute a business critical traffic? I mean besides internet breakout/LTE options. For example finding an additional route across the given SD-WAN sites and then updating their respecting routing tables, and by doing so enabling the business critical traffic to still flow through the premium underlay such as MPLS (and not to use internet breakout/LTE).
Appreciate your help. Any reference material would be great.
Thank you!
