Hi Robert,

To my feeling we have already agreed to treat them separately?

While on the surface they may look the same "Oh I just want my BGP to come up" if you look under the hood and say compare iBGP vs eBGP via L2 switch vs eBGP via p2p link they are really different animals in the same garden.
