[AusNOG] Cisco Q-in-Q config on AAPT e-Line

[James Mcintosh]

Hi Noggers,

I'm hoping one of the many smart people on the list can help me with my Q-in-Q issue on AAPT's e-Line (Ethernet).

We have an AAPT Ethernet Trunk Access at our core that terminates various customer Single Access services. Config on the trunk port that terminates the various single access services looks like so:

sh run interface GigabitEthernet1/0/21
Building configuration...

Current configuration : 217 bytes
!
interface GigabitEthernet1/0/21
 description AAPT Trunk
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 215-218,320,321,398
 switchport mode trunk
 load-interval 30
end

Pretty standard stuff. However here's where it gets complicated (to me). VLAN 320 needs to do Q-in-Q, encapsulating 3 other VLAN's within it (VLAN 8, 91 and 22)

Quoting from the AAPT product definition:
 
"AAPT e-Line services delivered end-to-end on AAPT infrastructure support customer VLANs transparently. e-Line services are designed to allow customers to configure and run multiple VLANs without any need to co-ordinate with AAPT.


To enable multiple VLANs across an AAPT e-Line service where one end is an Ethernet Trunk Access and the other end is either Ethernet Single-Service Access, the customer should configure the CPE at the Ethernet Trunk Access end with 802.1QinQ encapsulation and the CPE at the other end with 802.1Q encapsulation."


So my question is, how do I get visibility on the core switch of VLAN 8, 91 and 22 which are encapsulated within VLAN 320?

Your help would be VERY much appreciated!
