Q-in-Q with RUTX50

Hello!

I have a project which I need to use the S-VLAN and C-VLAN concept using RUTX50 to carry customers VLAN (any-VLANs ID) through the S-VLAN (VLAN 500), through the other end of the link. Together with VLAN 500, I also need to use VLAN 10 for monitoring traffic (and point to point).

I can find a detailed explanation on how to achieve this, but this is what I have in mind, need expert advice whether these are correct or otherwise.

  1. In VLAN > Port Based, add VLAN10 and VLAN500 and set WAN port as Tagged
  2. In VLAN > Port Based, set VLAN500 as Tagged in LAN1 (to customer)
  3. Remove VLAN 2 from WAN port (Off)
  4. In VLAN > Interface Based, Add New Instance (Customer), and set: Tag = 500 (the S-VLAN), Type = 802.1q, Parent Interface = eth1.500 (referring to LAN1 - tagged with VLAN 500).

Repeat the same to other RUTX50.

Customer will connect his switch to LAN1 and free to use any VLAN ID between these two sites.

I can create new LAN interface and set physical = eth0.10 as a point to point IP between the two RUTX50 for administration purpose.

Appreciate comment and feedback.
