I've never had to configure any sort of layer two tunneling, so I'm not really familiar with my options. I'm pretty sure there are many here who have done this, so I thought I'd ask. What we need to do is fairly simple. Here's a basic map:
DeviceA ------ [6500] -------(fiber run to different site)-------- [6500] ------- DeviceB At the moment, the devices on each end are connected to layer three interfaces, not switchports, and the link between the 6500s is routed. We've run into a legacy issue and the solution is to put DeviceA and DeviceB on the same vlan. However, we do not want to change the routing between the 6500s. We really, *really* want to leave the routing in place. Switching to an all layer-two design causes some other headaches for us that you don't see because of my simplified diagram. So, I think some sort of layer two tunneling is in order. What are our options if we want to make DeviceA and DeviceB think they're local to each other and in the same LAN? I've heard of L2TP and of various MPLS techniques that might solve this, but I've just never needed to use them and really know nothing about how they're configured or if they're even legitimate options. Any thoughts? Many thanks!
