Jun 12th, 2009

i have two routers connected wtih fiber, not over the internet but think of a gian LAN. Is there any way to do a layer 2 encription between these two routers? or may be just a ipsec tunnel?

Thanks

Thanks for the help!

What if two routers on the same subnet? Will that works for L2L IPsec? I have done L2L on different subnet but just not sure if this will work on two routers on teh same subnet.

interesting, thank you!

Do you have any sample configure for same subnet L2L IPsec?

It would come down to routing at that point.

If each of your routers only know to send the traffic for that subnet across the tunnel, then it will work, however, if both have the same connected subnets, then it won't work, as they know of those subnets locally. In that case you would have to NAT the traffic and encrypt it.
