Joe, The majority of RBridges will be deployed in backbone where they will be connected by point-to-point links. The classical case will be 10GE links (which are only full-duplex). There will be no bridges between them. What we are asking is a sentence that guarantees a simplified interoperability in this case. I don't see what harm it can do. -- Silvano > -----Original Message----- > From: Joe Touch [mailto:touch at ISI.EDU] > Sent: Wednesday, October 03, 2007 10:06 PM > To: Silvano Gai > Cc: Dinesh G Dutt; Rbridge at postel.org; Caitlin Bestler > Subject: Re: [rbridge] Consensus Check: Point to Point links > > I can't speak for others, but I'm completely lost on this point.
