DTLS connection im Vmanage

[himanshudwivedi]

Hello,

I am new to SDWAN

I have 1 VManage, Vsmart and Vbond and all are showing active. But when I execute command in Vmanage it is showing 4 DTLS connection with vBond in which Peer are 0,1,2,3 all are showing up but System Ip is only showing in 0 Peer, in 1,2,3 it is showing 0.0.0.0 , so what does it mean why it is making 4 connection.

Same thing happening with Vbond it is showing 4 DTLS with Vmanage, with all Peer 0 and showing Vmanage system ip, why is this happening or it is default behaviour.

hi,

We will have (d)TLS connection per core.
If you more closely, the port will be different
Something like 12346, 12446 and so on.
It is a way to distribute the load across the cores, so control connections are spread across and not pinned to one core.
The SD-WAN CVD link has more details. Link below:
