EVPN-VXLAN + QINQ #1513

Open Lolikololix opened 1 year ago

Lolikololix commented 1 year ago

Hi!
A make my EVPN-VXLAN lab in GNS3 with 3 SONiC(2 leaves and spine) and 2 mikrotiks. Mikrotiks as clients devices has vlan interfaces:

All evpn routes are present on all leaves and spine, but traffic passes only in vlan 150.

Can SONiC handle qinq in vxlan? I don't understand its behavior or it just drops traffic.

Linux with traditional bridge swap svlan to vxlan header and keep cvlan(inner) without change or keeps all tags without swapping in vlan-aware(vlan-filtering) bridge. Other vendors have options for working with qinq that keep all vlan tags under the vxlan header.

You might be hitting firewall rules as the 8 ports in GNS3 are emulated?
