Bridging across routed WANS: HOW?

[rick.payne]

I have a customer who has the same subnet in 2 different locations. They need broadcast and multicast to go to each other. Neither site has duplicate address to the other. previously connected by switches. Noe need to connect them by routers over a routed WAN link.

It's not usually a good idea, but with IRB you can do it.

Here's a good doc:
