Cisco QinQ double tagging

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 Carlton,

please let me send you this file from Cisco.. It is one of  my favourite for the way it explains this topic

 

Take Care

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

Carlton
