L2VPN ARP tables changes

This post was originally published on this site

Hi everyone:

I have the following scenario:

Site 1: NSX Edge with L2VPN Client
Site 2: Edge in vCloud Director dedicated to L2VPN Server (no internet access, only to extend VLAN)

Egress Optimization Gateway Address is not enabled on both sites.

At the time of lifting the L2VPN tunnel, the VLAN is extended without problems, however, some VMs in Site 1 begin to lose connectivity to the internet, and when checking the ARP table of the VM, the gateway IP address shows the MAC of the Edge of the L2VPN.

VMs at Site 2 communicate with VMs at Site 1 without problems.

Why might VMs at Site 1 recognize Site 2 Edge as a gateway?
