Has anybody done a 'spanned' lan over a layer 3 connection (PRI terminating on two routers) so that devices on both ends are on the same LAN? I think Cisco calls it IRB, and they have examples on one router, but my need would be to have it on two routers.
I know it is bad design and it isn't my choice, just may need to make it work.
You can use IRB and GRE tunnels. I had to do this for a company that we acquired that was using their routers to bridge traffic over frame-relay. To give them a migration path I configured layer 3 subnets across the frame-links and used GRE tunnels and bridge groups to bridge the ethernet to the GRE tunnels. It was a very ugly configuration and I wouldn't recommend it as a long term solution. If your networks have a large number of Windows computers, the NetBIOS activity severely affects the performance of your WAN link.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
