The goal I've been told to meet is that VLAN X in location Y must also exist in Location Z. Same subnet, etc.
The two locations are interconnected via IP. I've looked at all I can think to look at regarding GRE tunnels but the whole 'transport of a vlan' over one just has not jumped up and bit me yet. So any links you can provide (Adam) to get me in that direction would be helpful. Like I mentioned earlier, I know about L2TPv3 but can't use it due to code limitations on these 6500s. Unfortunately right now a code upgrade isn't going to work. My other option is to simply implement a VPN between the sites with the users plugging into a vlan I make up over there and then VPN them over to location Y and do a translation to get them where they need to be. It's actually pretty simple to set that up and I'm reasonably sure that it will meet all the needs. Right now I'm trying to remember where in the Docs the 'tunnels' are. -Mike From: Joe Astorino [mailto:[email protected]] Sent: Monday, November 02, 2009 3:25 PM To: Michael Lipsey Cc: Adam Frederick; [email protected] Subject: Re: [OSL | CCIE_RS] Routing a VLAN between sites What exactly do you mean "provide access to" ??? If you just need people at the other site to be able to access devices on that VLAN simple routing will do just fine. If you want devices on both sides to be part of the same actual layer 2 broadcast domain, that is a job for something like L2TPv3 like you said.

The actual topology is that we have an ISP that provides us connectivity between sites via their MPLS cloud. We are completely CE however. -Mike From: Adam Frederick [mailto:[email protected]] Sent: Monday, November 02, 2009 2:52 PM To: Michael Lipsey Subject: RE: [OSL | CCIE_RS] Routing a VLAN between sites What is between the 2 sites?

I've got a VLAN at one location that I need to provide access to from another location. Basically I need to tunnel the VLAN over IP. It is IP between both sites and the two end points are 6500s running 12.2.SX code. I had been looking into L2TPv3 but my code doesn't appear to support that. Any other ideas? Thought this might be a good place to ask. -mike CONFIDENTIALITY NOTICE: This electronic transmission (including files attached hereto) is intended only for the use of the individual or entity named above.
