Hi,Liboyer

Overlay Flow Control does not show routes to the VCG.
If you refer to the Route Table of the Edge, you will see that there is a path to the VCG.

regard,

Thank you for your reply.

Now, my problem is that VCG cannot forward edge traffic. When edge sends packets through the tunnel established by VCG and the packets are sent to VCG, the VCG directly forwards the packets to the directly connected router (the packets are original packets without tunnel encapsulation), so the router does not know how to reach the private IP address of edge. The router discards the packet. Please refer to my topology and router packet forwarding result. When I built my own tunnel from edge to edge, communication was normal. When I built my own tunnel from edge to edge, communication was normal.

Hi, Liboyer.

Is the path you want to communicate with the red line?
This path is from WAN to LAN.

Since this path will be underlay, I think it will be communicated regardless of the VCG.
