There is a way that I know, but it's not pretty. Build the QnQ to an additional port on the device you want to inject/break out the VLAN from. Make sure it is mode dot1q-tunnel. Then loop it (cross connect it) to another port on the same device and make that is a trunk port. Specify the VLAN you want and you're done.
I've done this a few times and it works just fine. As mentioned, it is not very elegant and someone might know a better way to do it, like tagging the native. The method described above can inject/break out multiple VLANs, where as fiddling with the native cannot. Good luck. ----- Original Message ----- From: "Skeeve Stevens" <[email protected]> To: [email protected] Sent: Monday, March 23, 2009 2:57:14 AM GMT -05:00 US/Canada Eastern Subject: [c-nsp] Pulling a VLAN out of a QinQ trunk Hey all, Say I have a QinQ VLAN from one place to another... and it goes through a few switches. If I wanted to do something to one of the VLAN's inside the QinQ, is that possible? Examples of things I would like to do. - SVI with a IP address in an intermediate switch - Push it into a trunk on an intermediate switch to break it out I've googled, but when I got to PPPoEoQinQ my mind exploded with too many layers! ...Skeeve -- Skeeve Stevens, CEO/Technical Director eintellego Pty Ltd - The Networking Specialists [email protected] / www.eintellego.net Phone: 1300 753 383, Fax: (+612) 8572 9954 Cell +61 (0)414 753 383 / skype://skeeve -- NOC, NOC, who's there?
