[c-nsp] BGP DFZ convergence time - FIB programming

[Phil Bedard]

Nicolas covered the RIB speed in the blog as well, and had varying results, but on average about 10s for today's full table.  The bottleneck in the operation is usually the advertising router, not the local router populating the RIB.  I don't think there was a test where the FIB took more than 30 seconds.  

Thanks, 
Phil

    I don't have any of these boxes (or chipsets) in my network, but out of
    curiosity, how long does it take to load the same routes in RIB,
    depending on if these are learned via iBGP (from a route reflector,
    likely) or via eBGP (from an upstream provider, for example)?
    
    Mark.
