How about IRB bridging across? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Matt Hill Sent: Tuesday, November 03, 2009 8:38 AM To: Michael Lipsey Cc: [email protected] Subject: Re: [OSL | CCIE_RS] Routing a VLAN between sites
That sounds rather odd. Two distinct sites in the same subnet? Apart from the tunneling already mentioned, I hope you have mammoth bandwidth because all your servers/hosts will think they are on the same LAN! If you do, I am sure you can ask the ISP to provide the tunneling for you. Ask for l2 VPN ax opposed to l3 VPN.

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; <mailto:[email protected]> [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: <mailto:[email protected]> [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?
