bgp best practice question
I need to make one of our data centers internet accessible, i plan to advertise a /24 out of our existing /22 network block at our new site. My question is for our main datacenter, is it a better idea to continue to advertise the full /22 or advertise the remaining /23 and /24 networks ? - Jon Heise
Depends on a few things, but the main questions are probably: Are the data-centers connected on the backside (VPN, etc. - could the new dc failover through the main dc)? Yes - /22 Will that /24 ever be used in the main datacenter? Yes - /22 $0.02 ~Chris On Mon, Jun 4, 2012 at 12:36 PM, jon Heise <jon@smugmug.com> wrote:

22 + 24. 23+24+24 makes no sense. There is no reason to fear getting extra traffic, as traffic will plummet once hosts stop responding. -- ++ytti
