Consistent routing policy?

Hello, In reviewing our BGP routing policies last week, I realized that we are advertising our address space upstream in slightly different ways to our two upstream providers. For example, we might advertise a /21 to one provider and break that into two /22s when advertising it to the other. (The

Re: Consistent routing policy?

Thanks, Mark. So the discrepancy between what's being advertised (/21 vs /22) shouldn't cause any issues? That's the part I got a bit confused about. I don't see how it would, but I wanted to make sure. Thanks, Ben On Mon, Sep 16, 2019 at 7:47 AM Mark Tinka wrote: > > > On 16/Sep/19 13:35, B

Cogent sales reps who actually respond

Hi fellow network operators, Do any orgs here have experience with a good Cogent rep? The rep we got via Cogent's website is unresponsive to even basic questions. It feels like we are dealing with a bot and copy-pasted replies. Thanks Ruldu

Re: Cogent sales reps who actually respond

The last time I dealt with them, it took a little over 3 months to get them to turn up basic BGP service. To top it off the sales rep was fired in the middle of our deployment. Cogent seems to have higher rep turnover than anything else I've dealt with. Buckle up and have fun! On 9/15/2019 4:1

When they do their cold calls I tend to answer «Call again in 6 months, if you are still with Cogent then.» Most sales reps don‘t survive that long. #SCNR -- Fredy Kuenzler Init7 (Switzerland) Ltd. Technoparkstrasse 5 CH-8406 Winterthur Switzerland http://www.init7.net/ > Am 16.09.2019 um 15:

Hi Ben, Prefix deaggregation and inconsistent announcements might work fine in the US where all paths are mostly of equal quality, but is the bane of my existence when it happens in regions like the Middle East or Africa where one transit used by a target ISP might be connected locally and the

Re: Consistent routing policy?

Ben, To make it a bit cleaner, you most likely want to send your aggregate (/21) to all service providers, and then if you choose to deaggregate and create more specific advertisements for traffic engineering purposes, you just advertise the relevant longer prefixes (/22's for example) on the spec

Re: Cogent sales reps who actually respond

Given their practice of harvesting whois updates in order to spam newly acquired AS contacts, any time it is my decision, Cogent is ineligible as a vendor. I’ve had no trouble getting their reps to respond when the decision has come from above, but I prefer to avoid doing business with them. O

Re: Cogent sales reps who actually respond

Probably going to shoot myself in the foot but we have been with Cogent for 14 years and I have nothing but praise for their Service,  NOC and my Sales Rep who is top notch. As usual, everyone's mileage will vary but it seems I am on the luckier side in having this good experience with Cogent

Re: Cogent sales reps who actually respond

Our sales rep has been great, but unfortunately, for him, every time he calls and I ask if Cogent is going to get me IPv6 transit to Google, he has to say no, and then I tell him I can’t purchase any more circuits. From: NANOG on behalf of Owen DeLong Date: Monday, September 16, 2019 at 9:20 A

For any router which receives both announcements, longest match always wins over all other BGP tie-breaking criteria. This is almost always summarized as “Longest Match always wins” because virtually any engineer recognizes that the winner is selected only from the available contestants, not fro

Regarding the latency, it looks like Cogent isn't much worse than anyone else. When they are bad, there's typically someone else bad there with them. https://www.noction.com/wp-content/uploads/2019/09/TIER1-AUG-2019.pdf - Mike Hammett Intelligent Computing Solutions Midwest Interne
