Description (partial)

Long convergence times of around 5-10 seconds seen on BGP process no shutdown.  This is due to the BGP "supress-fib-pending" command not taking effect in this situation.  Due to this, the N9508 advertises BGP routes before programming in the hardware.  This results in traffic being dropped.

When executing the "no shutdown" command under the BGP config to restore the BGP process long convergence times are seen.
