RE: Getting pretty close to default IPv4 route maximum for 6500/7600 routers.
From: NANOG [mailto:nanog-boun...@nanog.org] On Behalf Of Irwin, Kevin Sent: Wednesday, May 07, 2014 4:39 PM I¹m really surprised that most people have not hit this limit already, especially on the 9K¹s, as it seems Cisco has some fuzzy math when it comes to the 512K limit. I would actually be very surprised if someone would hit the 512K limit on ASRs. With 6500/7600 I can understand they've been around for ages and no one anticipated the 512k limit back then. But ASRs? When these where bough engineers must have known that 512k is not going to be enough. I guess one does some reading and tweaking before installing a box as a PE or Internet Edge. adam

Actually, it *was* anticipated. It's just that those who designed the ASIC didn't necessarily envision that it would still be in service, having gone through successive additional minor variations, for quite so long. --- Roland Dobbins rdobb...@arbor.net // http://www.arbornetworks.com Luck is the residue of opportunity and design. -- John Milton

Hi Jeff – I noticed the question posed here so thought I’d respond, perhaps at risk of stirring up a hornet’s nest given how long the last thread was. ;-) Anyway… there’s no congestion between Comcast and Level 3 connections, and we’re working collaboratively with Level 3. Given these facts, we have no reason to believe that Comcast is on their list. - Jason Comcast On 5/8/14, 1:18 PM, =JeffH jeff.hod...@kingsmountain.commailto:jeff.hod...@kingsmountain.com wrote: Level 3 accuses five unnamed US ISPs of abusing their market power in peering http://gigaom.com/2014/05/05/level-3-accuses-five-unnamed-us-isps-of-abusing-their-market-power-in-peering/ ...I’d love to see Cogent, Google and other providers release their data next, so even if the FCC doesn’t want to pursue this, a growing cry of consumer outrage could push the agency to do something about a very real and difficult problem that’s crippling access to video content on 5 U.S. broadband networks. Level 3 didn’t name names, but based on the deals Netflix has signed and the complaints it has made about ATT, I’m confident that ATT, Verizon and Comcast are among the five.

Anyway… there’s no congestion between Comcast and Level 3 connections, and we’re working collaboratively with Level 3. Given these facts, we have no reason to believe that Comcast is on their list. Sure, because Level 3 is already paying Comcast to deliver traffic to your paying customers, right? -- Hugo From: NANOG nanog-boun...@nanog.org on behalf of Livingood, Jason jason_living...@cable.comcast.com Sent: Friday, May 9, 2014 5:27 AM To: =JeffH; nanog@nanog.org Subject: Re: Observations of an Internet Middleman (Level3) (was: RIP Network Neutrality (was: Wow its been quiet here...

Level 3 didn’t name names, but based on the deals Netflix has signed and the complaints it has made about ATT, I’m confident that ATT, Verizon and Comcast are among the five. signature.asc Description: Digital signature

ROFLMAO — Party in Bellevue is more than likely to push it back up over 500K
again, isn’t it?
Sounds like a Dish commercial… (James Earl Jones voice):
When you put a bunch of network engineers in a party in Bellevue, you get a
bunch of drunk network engineers.
When you get drunk network engineers, you get interesting router configurations.
When you get interesting router configurations you get disaggregation of the
routing table for TE.
When you get disaggregation for TE, the routing table grows.
When the routing table grows, you hit half a million routes.
When you hit half a million routes, the internet starts to break.
Don’t break the internet. Don’t get half a million routes. Don’t let network
engineers party in Bellevue.
(No, I’m not actually opposed to the party, but I thought you might find the
commercial amusing).
