RE: Level 3 BGP Advertisements
No, that's not standard practice. I do this exact thing with Level 3 and have been for many many many years. Whoever is telling you this must be green. I would recommend adding the no-export community to your more specific routes if you can so as to be a good steward of the ever growing Internet IPv4 table. From: Nick Olsen [n...@flhsi.com] Sent: Wednesday, August 29, 2012 2:28 PM To: nanog@nanog.org Subject: Level 3 BGP Advertisements Greetings all. In practice, We've always advertised our space all the way down to /24's but also the aggregate block (the /20 or the /21). Just so there was still reachability to our network in the event that someone made the foolish mistake of filtering lets say prefixes smaller /23... Anyways, I've always thought that was standard practice. And its never been a problem. Until we brought up peering with level 3.. I noticed that while the /24's made it out to the world. The larger counterparts (2 /21's and a /20) did not. So, I start sniffing around. Find that I do indeed see the prefixes in Level 3's looking glass but they aren't handing it off to peers. So, Naturally, I land on this being some kind of prefix filtering issue and open a ticket with Level 3. They tell me this is standard practice. And If I want to see the /20 or /21's make it out to the rest of the world, I need to stop sending the /24's. Does this sound normal? Is what I'm doing (Advertising the aggregate prefix) a good rule of thumb? Any other thoughts?
