CenturyLink/Level 3 combined AS
Hey all, Are there plans for CL and Level3 to combine AS's into one network? If not, do they actively peer and route traffic through each other's networks at least? Basically we're looking at picking up 1G of CL and wondering if it's near the same quality as Level3 in terms of latency and packet loss.

I wouldn't expect them to be integrated for at least another decade. Global Crossing AS3549 still exists with over 2,000 peer ASNs, yet Level 3 acquired them in 2011. Time Warner Telecom was acquired in 2014 and it still has 89 peer ASNs. Centurylink bought Digital Teleport in 2003 and their ASN is still out there. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Darin Steffl" <darin.steffl@mnwifi.com> To: "North American Network Operators' Group" <nanog@nanog.org> Sent: Friday, June 7, 2019 11:01:46 AM Subject: CenturyLink/Level 3 combined AS Hey all, Are there plans for CL and Level3 to combine AS's into one network?

That '2000 peer ASN's' value is likely very, very inflated. I have prefixes that would look like I am peering with 3549 directly in many places that I do not. L3 has for some time had a partial as-merge community that you can set so that if you announce a prefix to 3356, they'll mirror it over to 3549 in the same location and strip 3356 from the as-path. The reverse also works for an announcement to 3549 mirrored over to 3356. They're doing some inter-as option c juju to make all that work. Doesn't change the point that 3549 is still around 8 years later and likely will be for 8 more, but yeah. :) I'm sure efforts to make that happen have a plethora of roadblocks such that it would cost 10x more to get rid of it than it would to just leave it as is and just shrink it when possible.

We have CenturyLink transit from old Qwest (AS 209) and old Level3 (AS 3356) in Chicago... when we ordered the more recent circuit, both sales and tech said that there's no plan to merge the ASes together at this time. They already had peering, so I assume that just expanded. We haven't had any issues with either. And BTW: when you say "CL" - those are just two of the large family of ASes that CL has bought. There's also old Savvis AS 6347, and other old Savvis (aka Cable & Wireless aka InternetMCI) AS 3561, and untold more Internet history... :) -- Chris Adams <cma@cmadams.net>
All new CL Internet get's provisioned on AS3356 You would need a strong case for them to put you on AS209 At this time they are not merging the two AS's And also define "quality" ;-) -Romeo From: NANOG <nanog-bounces@nanog.org> On Behalf Of Darin Steffl Sent: Friday, June 7, 2019 12:02 PM To: North American Network Operators' Group <nanog@nanog.org> Subject: CenturyLink/Level 3 combined AS Hey all, Are there plans for CL and Level3 to combine AS's into one network?

That isn't true in my recent experience. We just replaced an older L3 transit with a new CL one on different floors of the same building, and doing so involved moving from 3356 to 209. Interestingly, the CFA for the new circuit's attachment suggests it came out of the "L3" suite, not the "Qwest" suite (both on the same floor); so it seems that 209 is provision-able at former L3 facilities. Other recent entirely new CL turn-ups with us, out of rural COs belonging to Frontier, have also been with 209. --Eric

Got provisioned last year on AS209 when they turned up my ent Fiber with BGP. Could depend heavily on what services and where. -- Brielle Bruns The Summit Open Source Development Group http://www.sosdg.org / http://www.ahbl.org
Ok just so simplify things. Is Cogent or CenturyLink/L3 better for transit? On Fri, Jun 7, 2019, 3:00 PM Brielle Bruns <bruns@2mbit.com> wrote:

As usual, that depends. Gotta give us a lot more information than that. -Mike Bolitho On Sat, Jun 8, 2019, 6:10 AM Darin Steffl wrote:

Cogent is great, or worthless, depending on whether you like talking to Google via IPv6.

Cogent and "great" don't belong in one sentence in my opinion. It's usable though and their pricing is (if you push hard enough) simply unbeatable. I would pick L3 any day over Cogent if the pricing was the same. Kind Regards, Filip Hruska On 8 June 2019 3:36:26 pm GMT+02:00, David Hubbard <dhubbard@dino.hostasaurus.com> wrote:
