I was simply trying to point out that the "NAT is cancer!" war cry for IPv6 (without offering a better/more functional alternative) is a big part of why small businesses are so resistant to moving to IPv6.

Curious mostly about malformed updates coming from DOD ASN
by Drew Weaver 17 Jun '26

17 Jun '26

Howdy, I'm mostly just curious I've seen things like this before but more in the past 16 hours. Are other folks seeing these? Malformed UPDATE message received from neighbor (Lumen) (VRF: default) - message length 189 bytes, error flags 0x00000080, action taken "TreatAsWdr". Error details: "Error 0x00000080, Field "Attr-length", Attribute 40 (Flags 0xc0, Length 37), Data [c0282500]". NLRIs: [IPv4 Unicast] 55.27.156.0/24<http://55.27.156.0/24> 55.27.184.0/24<http://55.27.184.0/24> 55.74.158.0/24<http://55.74.158.0/24> 55.74.157.0/24<http://55.74.157.0/24> 55.67.156.0/24<http://55.67.156.0/24> 55.74.156.0/24<http://55.74.156.0/24> I'm wondering because it could be that the update itself is fine but my router cannot interpret it properly. Thanks everyone, sorry for noise. -Drew

Presentations may cover current technologies, soon-to-be deployed technologies, and industry innovation. Vendors are welcome to submit talks which cover relevant technologies and capabilities, but presentations should not be promotional or discuss proprietary solutions. The primary speaker, moderator, or author should submit a presentation proposal and abstract via the Program Committee Tool (PC Tool) at: https://www.nanog.org/meetings/submit-presentation/ - Sign in with your Profile Account - Select the type of talk you propose to present, and complete the form Timeline for submission and proposal review: - The Submitter will enter the abstract in the PC Tool prior to the deadline for draft slide submission. The PC Tool will not accept new submissions for NANOG 98 after this deadline. - The Program Committee (PC) will perform an initial review and will assign a “shepherd” to help develop the submission, typically within 2 weeks. - The Submitter will develop draft slides of the talk, if not already submitted with the initial proposal. Please submit initial draft slides early — the PC will not evaluate submissions until draft slides are available for review. (Slide templates are available on our Tools + Tips <https://nanog.org/program/tools-tips/> webpage under the heading NANOG Presentation Template.) - Panel submissions should provide a document listing bios for the moderator, panelists, and an intended topic list. - The PC will review the slides and will continue to work with the Submitter as needed to develop the topic and content. - DRAFT SLIDE DEADLINE Draft presentation slides should be submitted prior to the published deadline for slides (21 September 2026). - The PC will evaluate submissions to determine presentations for the agenda (to be posted on 28 September 2026). - Submitters will be notified whether their talks have been accepted. - The Agenda will be assembled and posted. - FINAL PRESENTATION SLIDES must be submitted prior to the published deadline for slides (12 October 2026 for in person + live remote presentations) - submissions will NOT be accepted through the PC Tool after this date. - Lightning talk submissions open for in-person attendees on 18 October 2026. If you think you have an interesting topic but want feedback or suggestions for developing an idea into a presentation, please email the PC ( nanogpc(a)nanog.org) and a representative will respond to you in a timely manner. Otherwise, submit your talk, tutorial, track, or panel proposal to the PC Tool at your earliest convenience. We look forward to reviewing your submission!

Cisco ASR 9004 Chassis and Licensing.
by andy＠chillercity.net 14 Jun '26

14 Jun '26

I am currently running an ASR-9010 and already own a pair of with a pair of A9K-RSP440-TR route processors along with an A9K-24X10GE-TR line card and some others, including an A9K-MPA-2X40GE. I'm thinking about adding some 100G capability, although I don't really need it yet. I also have a couple spare RSP880s and a spare A9K-24X10GE-TR. I have recently seen ASR-9904 chassis and A99-8X100GE-TR line cards for sale on the secondary market at reasonable prices, and I am considering building a lab router using: * ASR-9904 chassis * Dual A9K-RSP880-TR * A9K-24X10GE-TR * A99-8X100GE-TR I know there is also the A9K-8X100GE-TR, which would work in my existing 9010 chassis, but those cards seem to be both expensive and hard to find. My question is mostly about licensing. If I assemble this system from used components, will I encounter any licensing issues that would prevent the router or the 100GE interfaces from operating? I'm not asking about advanced features such as EVPN, HQoS, MACsec, or large-scale VRF deployments. My primary interest is basic IPv4/IPv6 routing, BGP, and operation of the 10GE and 100GE interfaces. Has anyone actually deployed or labbed a 9904 with an A99-8X100GE-TR and RSP880s using equipment acquired on the secondary market? Specifically: * Do the A99-8X100GE-TR ports come up and pass traffic without additional licensing? * Are there any Smart Licensing requirements that would prevent normal operation? * Are there any known limitations when using these cards in a standalone lab environment without an active Cisco support contract? I have tried contacting Cisco and a few resellers, but I have not been able to get a clear answer on whether any licensing is enforced for basic operation of the A99-8X100GE-TR. I am hoping someone with real-world experience can clarify what actually happens in practice. I am also not sure how I would go about obtaining any required licenses if I eventually decided to move the system into production. Cisco Smart Licensing makes my head hurt.

FRR for BGP route reflectors?
by Tom Samplonius 09 Jun '26

09 Jun '26

Hi, Is Free Range Routing (FRR) a viable choice for a pure BGP route reflector for a regional ISP with ~ 35 routers? A mix of L3VPN-MPLS and BGP-EVPN services. Full transit, plus some peering. About 5 x L3VPN instances, and maybe 500 x EVPN-MPLS instances. I don’t see a lot of posts of people using FRR for RR. And not a lot of people reporting issues, so maybe it is just the perfect RR solution? Tom
