Hi, i would like to achive the following configuration that works on Cisco Nexus, on MikroTik HEX s models.
CISCO-NX-ISP-SW01 & CISCO-NX-ISP-SW02:
Eth1/1:
Switchport access vlan 1500
switchport mode dot1q-tunnel
Eth1/2
sw mod tr
sw tr all vl 1500
C2960-ISP-SW01 & C2960-ISP-SW02:
Fa0/1 & Fa0/24
sw mod tr
sw tr all vl 1500
C2960-Cusomer-Site1&2
sw mod tr
sw tr all vl 10,20
I would simply like to put all the vlans (10,20) that i get from Cisco 2960s from Customer-Site1&2 inside vlan 1500 on MT-HEX-ISP-SW01, create trunk beetwen MT-HEX and C2960-ISP-SW01&2, and take all customers vlans inside Vlan1500, and “pack them out” on the other MT-HEX toward Customer site2
Method1:
I tried two diffrent things from the link bellow, 802.1ad with SVID (doesnt work), when i sniff the packets on C2960-ISP-SW01 port Fa0/1 i can see the packet (instead vlan10, here is used vlan212):
But when i monitor session on the same switch on the port fa 0/2, this packent wont get forwarded so i guess the Cisco C2960-ISP-SW01 discard this packet. If i do the same sniff when using nexus i can see only vlan212 tag not the vlan1500 tag.
Method2, tag stacking, or double CVID tag,
This works, but when i do the same sniffing, i see just untagged traffic, so i guess, the Cisco just strips off the first tag, and than send the traffic untagged, not sure about this one how exactly does it work but the traffic does come from customer-site1 to customer-site2. Iam not sure if this method is really ok and correct ? Anbody willing to explain,…Again when sniffing when using nexus i can see the vlan212 tag.
Cisco Nexus method:
The same sniffing, i can see that the packet gets through, and can see the vl212 tag

Iam sure someone up here do this every day 
I would be really gratefull, if somenone let me know what is the “most proper” way to do this on MT-HEX switches/routers.
