SD-WAN vEdge cloud control connection will not coming up

mannycho — Sat, 18 Jun 2022 19:36:54 GMT

Hello,

I have three sites with vEdge cloud installed and two kind of transport; internet and MPLS. I configured the internet transport on all vedge clous devices and the control status were Up in vManage. When i configure the MPLS transport on all vEdge cloud devices, control status for all 3 devices go into Partial status. Checking connection history on the vEdge devices and i have DTLS connection Failure. Below is the output, how can i fix this issue

Your MPLS does not have connectivity in cloud controllers, right? Enable it or configure interfaces to work without control connections.

Hello,

The controllers are on premise and I ping the MPLS interfaces on the vedge cloud devices from all controllers.

Seems you have connectivity. Is there a firewall in front of controllers? Connections are initiated from edges, they must be allowed.

Are dns servers reachable via MPLS?

I am not using FQDN but IP address for communication between the controllers and vedge. I am not sure how DNS comes into play why DTLS is failing between vbond and the MPLS interface. I am confirming again that these vedge routers have their control status Up when only the internet interfaces are configured. As soon as I bring up the MPLS interfaces the control status goes into Partial
