BGP visibility for /24 End User Allocation
Long time on-again-off-again lurker. Looking to multihome in the most efficient mode. Our two upstreams are AS11530 (Embarq) and AS10796 (Time Warner). Diverse routed fiber from each at 10Mbps. Our traffic profile is highly asymmetric as a consumer of bandwidth (12-15Mbps average inbound aggregate, 2-3Mbps aggregate very bursty outbound). Years ago when I tinkered with BGP there were substantial issues with getting any prefix too small through filters to see the "greater Internet" (IIRC it was a /19 at that time). Given we really could justify a /24 realistically, what is the current status of filtering in terms of having that /24 get to the "vast majority" of the Internet given the two providers in question? Thanks for any advice in advance. EKG

A /24 is has been the gold standard for a while, you shouldn't have any problems. ~Seth
We have routed a couple of /24s via BGP for a long time. 10+ years for one of them. We have never had any issues. If you get an End-User assignment from ARIN, it is probably even easier than getting providers to route a /24 out of another provider's space. -Randy -- | Randy Carpenter | Vice President - IT Services | Red Hat Certified Engineer | First Network Group, Inc. | (800)578-6381, Opt. 1 ---- ----- Original Message -----

Shouldn't be an issue. We're advertising 4 x \24s and using much more BW. David. On Fri, Sep 23, 2011 at 2:29 PM, Eric Germann <egermann@limanews.com> wrote:
