6.1(2)I1(1.144)

Description (partial)

Symptom:
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.

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