Cisco QinQ double tagging

[Carlton Patterson]

Hello Experts,

I need to configure QinQ on my main interface before I can configure double tagging on sub-interfaces.

The problem is we have customers hanging off of the main interface. Can some please tell me what will be the impact on our customers if I configure the main interface with QinQ in a production network?

Cheers

Carlton

Hi Alessio

Thanks for responding.

I should have explained that the device I'm going to configure QinQ on is a GSR 12410. I just need to know if our customers that hanging off the sub-interfaces will be impacted when I configure the main interface with QinQ?

Cheers
