Replicating a Cisco QinQ Config

Hi Guys,

I am trying to figure out how to replicate a current config we have on a Cisco 9500 on one of our Extreme SLX 9640’s. The setup is basically we have a 100G port from a provider in an NNI style, so they shove multiple VLAN’s at us down this NNI for circuits. We then have 10 access routers that answer PPPoE requests on all these VLAN’s. We currently have this setup in a QinQ config on the cisco. All of the ports are part of the same QinQ tunnel, so can all answer the requests and see the traffic.

I have put the below config together which i think will achieve this, but not sure if its right and/or if there is a better way of achieving this. All advice and comments appreciated 🙂

bridge-domain 700 p2mp
pw-profile default
logical-interface ethernet 0/25.700
logical-interface ethernet 0/26.700
bpdu-drop-enable
local-switching
!
interface Ethernet 0/25
tag-type 0x88a8
switchport
switchport mode trunk-no-default-native
no shutdown
logical-interface ethernet 0/25.700
vlan 700
!
!
interface Ethernet 0/26
tag-type 0x88a8
switchport
switchport mode trunk-no-default-native
no shutdown
logical-interface ethernet 0/26.700
vlan 700
!

Thank you!
