Extending VLAN

I have a CISCO 4003 L3 switch with several VLANs . I need to extend just one of

the VLAN across a WAN to another site.

What is the best way to do this ? ( bridging ?)

Re: Extending VLAN

It is the only way (bridging). But, it will not pass the vlan ID so, it will only work for one vlan. But, I do not reccommend doing bridging. Please use a different subnet and route.

Re: Extending VLAN

I must have the same subnet for both segments and also I don 't need the VLAN ID to pass through. , so I think the bridging is the only option.

Can I do some filtering for unwanted MAC addresses over the WAN link to eliminate unwanted traffic over the WAN ?
