One of the more spectacular failures I've seen was a bug in a network core router that caused bad into to be carried by 
all of that same vendor's routers across the core to the edges (made by a different vendor) which promptly barfed and 
locked up.  

So I'd be cautious about saying "vendor X for one layer, vendor Y for adjacent layer" as a multi-vendor strategy.
