AS4565 contact
by Dorn Hetzel 31 Aug '12

31 Aug '12

After emailing some of the usual addresses without any luck, I am wondering if anyone might be able to point me towards a contact for AS4565 who could assist me with getting the announcements of some prefixes they shouldn't be announcing cleaned up? Please feel free to email me directly with any clues (or beratement for some obvious place I could have found the information if only I was smarter or tried harder :) ) ... -dorn

Color vision for network techs
by Berry Mobley 31 Aug '12

31 Aug '12

Hello, Do any of you do any color vision screening in your interview process? How do those of you with color vision impairments compensate? I'd never considered this until I was in one of our facilities with my son (who has limited color vision) and we had a discussion about the LEDs. He could only determine on/off - not amber/red/green on the equipment we had. I'm wondering if we need a color vision requirement (or test) as part of our hiring requirements. Berry Mobley

XO outage in NJ/NY?
by chris 30 Aug '12

30 Aug '12

Anyone heard anything about an XO fiber cut in northeast? We have had a bunch of issues with some DID's in NJ today and one of our carriers forwarded a a vague statement from XO: *XO Communications is currently experiencing a fiber-cut which is causing a service interruption for some markets in the east coast region. Users may experience DID failures for numbers in NY, NJ and other surrounding areas. They are working on fixing the issue but unfortunately have not provided an ETA at this time* Just curious how widespread the effect is and if anyone knows anything more about it thanks chris

mac limit per VPLS domain
by Adam Vitkovsky 30 Aug '12

30 Aug '12

I'm wondering what would be the sane default MAC limit per VPLS domain as well as per port assuming the RSP can hold up to 512K MAC addresses please? I believe the answer would partly depend on the business model (like I can start with 2 MACs per port and 50 per domain and have customers to pay extra for additional MACs) as well as expected number of VPLS customers/domains Thank you

[NANOG-announce] Call for Volunteers -- NANOG Education Committee
by Steve Gibbard 29 Aug '12

29 Aug '12

(my apologies to those receiving a second copy of this. The first copy ran into a mail filtering issue and didn't go out to most of the list) At the Vancouver meeting in June, I presented a preliminary proposal for a NANOG education initiative, which would put together a NANOG-created educational program for junior (and possibly more advanced) network operators. There was broad support from the community, and now it's time to refine the idea and turn it into something that can be implemented. We are seeking volunteers to join the Education Committee and work on the final proposal and its implementation. Among the issues that need to be decided are: - What format should the classes have? - What subject matter should they cover, and what should the curriculum be? - Who should be teaching them -- volunteers from the community or paid instructors? - Where should the classes be taught? At NANOG venues before, after, or during the conferences? At independent sites at non-conference times? - Cost structures: What should the classes cost and what will be included? - Other sources of financial support: Tuition? Sponsorships? Donations? Subsidies from the NANOG conferences? - And all sorts of other issues The expected commitment from members of the Education Committee will be as follows: - Attend bi-weekly conference calls - Research issues as needed, and provide feedback to the group The goal will be to have a reasonably solid proposal in time for the October NANOG meeting, and a final proposal in time for the February meeting. If you are interested in volunteering for this committee, please contact me. Thanks, Steve Gibbard NANOG Board scg(a)newnog.org _______________________________________________ NANOG-announce mailing list NANOG-announce(a)nanog.org https://mailman.nanog.org/mailman/listinfo/nanog-announce

I hear you guys, It's done that way for a bit of traffic steering. If I could get away with just the aggregates I would, Trust me.

Re: Level 3 BGP Advertisements

Thanks for the input Jon. I should note that is exactly what we are doing. The /24's are actually tagged with the advertise to customers, prepend to peers community.

No. I announce to Level3 our IP space and 2 subnets of each CIDR (i.e. /17 + 2 /18 subnets of that /17, etc.), but I use community tags (and other tricks) to mark the more specifics as advertise to [certain] L3 customers only, and let the less specifics out to the world. The only problems I've had with this have been when L3 peers have become customers, and one L3 customer doing something odd (never did find out what) that caused them to effectively null route our space until I kept them from seeing the more specifics (creative abuse of loop detection). Level3's prefix filter for your session should be built based on IRR data. If it's not doing what you want, you probably haven't setup the IRR data properly. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
