bgp is running on a network device, will the route advertisement and FIB programming(basically populating entries in hardware) occur in
Or does it occur sequentially, meaning, first the FIB is programmed and then the routes are advertised?
Que2. Ideally if a network device advertise the routes before FIB programming, this will lead to traffic blackholing/traffic getting dropped. Is that correct understanding?
Que3. How about
withdraw routes ?
