What is the most popular deployment for metro network

Hi there,

I'm wondering what's the most common deployment of metro network between two physically separated buildings ?

Should they have the same subnet ? or a different one at each side ?

thx

Garry

I have seen it implemented both ways, with the same subnet of both sides (especially if the provider supports Q in Q tunneling) or with separate subnets on both sides. I would say it is more common to have separate subnets on both sides.

Like Rick, I've seen both.  Much often depends whether there's a real "need" to extend L2 and/or equipment already on-hand.
