Re: Q-in-Q in QFX-5100

Without seeing your configuration, it means someone would have to look at your network etup and write the whole thing out fro you. It would be a lot more helpful to post the relevant configuration where one can look and see if maybe you are missing a litle bit, or a simple typo. Also which method are you trying to employ? Other than that one may simply point to articles which you have already gone through.

• Using the Different Mapping Methods
• Configuring All-in-One Bundling
• Configuring Many-to-Many Bundling
• Configuring a Specific Interface Mapping with VLAN ID Translation Option
