Hi I have an EX2200 and 2 SRX_240 interconnected. the SRX is just doing switching (mode packet-based), no security zones/policies.
Network diagram attached
The challenge is between the 2 SRXs is a Wimax link and the provider telling me, for the vlans to pass through the Wimax link, i need to double tag the traffic on the two SRXs (QinQ between SRX1 & SRX2).
from the juniper documentations, i have read that the C-vlans should not be defined on the device doing the QinQ, in this case the SRXs. the QinQ device recieves the frames with C-vlan tag and it just add the S-vlan tag on top. SRX2 is OK with this since its not droping/picking trafic for this vlans. its just a pass through device.
SRX1 is where i have the C-vlans defined and i am having challenge how to pass this vlans to the QinQ pipe.
Among the three ways of doing QinQ , SRX 240 supports only one method:!
- Map All-to-one (map all the C-vlans recieved to one S-vlan).....supported
- Map many-to-one (map some C-vlans to one S-vlan)......NOT SUPPORTED ON SRX240
- Map one-to-one (map single C-vlans to single S-vlan)......NOT SUPPORTED ON SRX240
Reminder: diagram attached for clarification.
apreciate your help.
Thank you all.
