Scenario 2:

After completing the branch activation activities for all required branches, the network administrator attempts to test connectivity between the various branches and between the hubs and branches. The administrator notices a lack of connectivity despite being certain that configurations have been complete. The administrator also observed that several users are reporting intermittent connectivity to some of the applications they are accessing. Other users are reporting no access to these applications. Other users at some of the branches claim they cannot get to certain public resources. The administrator wants to ensure that all sites can talk to each other and all resources are accessible.

Exhibit.

The SD-WAN Edge at this location has been activated. It is incapable of establishing any overlay tunnels. Due to this being an internet only branch, no underlay connectivity is present to the hubs. The SD-WAN Edge is connected behind a firewall and the security team states that all necessary ports are open.

How can this issue be resolved?
