Hi all,


From my reading thus far, I know that one can use 802.1 Q tunnel to pass VLAN across a WAN link. My questions: is it possible to pass more than one VLAN across a WAN link? Does anyone has a sample configuration?

Yes, you can do EoMPLS or L2TPv3.

I am more thinking of the L2TPv3 route: Would this work?


Location A:


int G9/48

description Link to Location A 

switchport  

switchport trunk encap dot1q  

switchport trunk native vlan 1001

switchport trunk allowed 5,7,13-15,21,35,99  

switchport mode trunk 



Location B:


int G9/48

description Link to Location B

switchport  

switchport trunk encap dot1q  

switchport trunk native vlan 1001

switchport trunk allowed 5,7,13-15,21,35,99  

switchport mode trunk 



I also think that the service provider has to support this. Correct?

Yes, we are thinking of ordering a fiber link with our SP and connecting it to our 6509...

Then your ISP will need to support 802.1q on their network. 6500 doesn't support L2TPv3.

Thanks. What can I use with the 6509. Would that sample configuration work with the 6509 if the SP supports 802.1Q?

If your ISP supports some type of LAN service to allow 802.1q, you just have to configure the ports as trunk ports, that is it.

Perhaps 802.1QinQ might work?  It would assume that you have a trunk available from your isp.
