Question:
1) Can I turn off (disable) "BGP general scanning" (command 'bgp
scan-time <5-60>') ? Is this a good idea in my case ?
That seems unlikely to be a good idea.
Thank you Alex.
But can this idea be realized at all? Just by default, bgp-scan occurs
every minute and it can only be changed by specifying the interval from
5 - 60 seconds. And it seems that it's impossible to turn off this
feature at all?
2) Can I perform "BGP general scanning" on a specific processor core,
not chaotic ?
IIRC, bgpd is entirely single-threaded. It should be trivial to bind
it to a single core using taskset on Linux (or the equivalent, on
another OS). You can do this while it's running, or you can start it
that way - modify the rc file that starts quagga & bgpd (or whatever
you're using to get it started on boot).
