Re: Nexus 5K vPC Peer link 1Gb over OM2 Fiber

I would agree that vPC doesn't forward much data under normal
circumstances... But what about forwarding mechanism in failure scenarios?
If not addressing these during design, then one learns the hard way if the
unfortunate situation happens. (ie switch failure down stream on chassis
one causing forwarding only on chassis 2 but also a link failure on chassis
two upstream to router)

The whole concept of multi chassis solutions is to provide HA in
failure scenarios which won't interrupt or cause severe limitations to data
forwarding. If not setting up the vPC peer link for such scenarios, than
why go with a multi chassis solution at all?
