QnQ

SwOS

I am hoping this has not been answered in other posts but I can’t find it.

The Questions is this. I need to be able to have the RB250GS do QnQ tunneling. I.E. port 1 is an uplink port to my network. port 2 is the customer handoff port. Whatever the customer passes me to port 2 is encapsulated with a VLAN Tag of “whatever” on ingress and on egress that tag is stripped. then passed to port 1 for transport across my network. I use the outer tag for tunneling though my network.

I can also do this at my core network level with my switches but i would need to append a native vlan to there packets but not strip or change there ip information in doing so . Just simply adding another C tag to the packet.


Can this be done with the RB250GS.

thank you

Currently it is not supported. But this feature might be implemented in the future.

SO tunneling is not support is the switch 802.1ab compliant so i can add a service tag in front of the other taggs on the ip packet. i.e. if a packet comes in with a vlan tag of 25 can i add vlan 26 in front of it. IF i can do this then i can have my carrier switches do the rest.

OK.. Will try that..

Thank you.

Is there support QinQ in swOS RB260GSP?

QinQ is not supported in SwOS

It should pass tagged frames untouched if ‘VLAN mode’ is set to ‘optional’. You could configure forwarding according to your needs and let the RB work in sort of VLAN trunk mode providing minimal isolation..
