Passing multiple VLANs across WAN

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?

Regards,

Yes, you can do EoMPLS or L2TPv3.

Re: Passing multiple VLANs across WAN

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?

Before answering that, how is the connection/design looks like? You are showing me some config off a 6500, are you connecting that port into the SP directly?

Just some reading material for L2TPv3

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

Re: Passing multiple VLANs across WAN

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

Re: Passing multiple VLANs across WAN

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

Re: Passing multiple VLANs across WAN

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.
