Cisco Nexus VXLAN w/vlan-aware-bundle ?
by Adam Thompson 03 May '23

03 May '23

Does anyone here use VXLAN on Cisco Nexus gear in the "vlan-aware-bundle" mode (RFC7432 §6.3), not the "vlan-based" mode (§6.1)? If so, could you please contact me directly to explain how you did so? Much appreciated, -Adam Adam Thompson Consultant, Infrastructure Services [cid:image004.png@01D97DB7.68236EA0] 100 - 135 Innovation Drive Winnipeg, MB R3T 6A8 (204) 977-6824 or 1-800-430-6404 (MB only) https://www.merlin.mb.ca<https://www.merlin.mb.ca/> [cid:image003.png@01D97DB7.67506730]Chat with me on Teams<https://teams.microsoft.com/l/chat/0/0?users=athompson@merlin.mb.ca>

Spectrum networks IPv6 access issue
by Tom Rini 03 May '23

03 May '23

Hey all, I'm posting this here in hopes of getting the attention of someone that can get this issue resolved, or at least an internal ticket filed. I've tried the customer-facing tech support and not been able to get such a thing done. In short, from within Spectrum's US IPv6 network (verified in both North Carolina and Ohio), dfw.source.kernel.org (2604:1380:4641:c500::1) is unreachable and connections time out. This site is otherwise fine and globally accessible via IPv6, tested on both Qwest and T-Mobile hosted systems. This is a regression from some time in early April this year. -- Tom

100G-LR1 (DR/FR)
by Jared Mauch 03 May '23

03 May '23

The common tech is 100G-LR4 these days - I'm wondering how many operators are supporting the LR1 to allow its use on 400G and future 800G optics as those use breakout to support 100G ports. Would you rather do a 400G port on a router vs 100LR1? Curious what others think. Sent via RFC1925 compliant device

Re: Best Linux (or BSD) hosted BGP?

VyOS uses FRR, but they used to run quagga. And most bsd(?)/linux package managers has frr in their repository so maybe that could be something to look at?

BGP Books
by Lyndon Nerenberg (VE7TFX/VE6BBM) 29 Apr '23

29 Apr '23

It has been a couple of decades since I've done any BGP in anger, but it looks like I will be jumping into the deep end again, soon, and I desperately need to get up to speed again. There seem to be a lot of good guides out there from Cisco, Juniper, and the like, but naturally they are very product oriented. What I'm looking for is more like the Stevens networking bibles (i.e. "BGP Illustrated Vol I and II"). Something that covers more than just the raw protocols, and includes things like RPKI. (The world sure has changed since the last time I was doing this!) Any/all suggestions welcome. Thanks! --lyndon

Facebook IP Geolocation
by Peter Potvin 29 Apr '23

29 Apr '23

Hey all, Recently a customer reached out to us regarding an IP of ours in Canada that Facebook is somehow placing within China, despite our geolocation in other databases showing up correctly as they're ingesting our geofeeds as we had requested. Does anyone know which geolocation databases Facebook uses, and if possible a contact at Meta we can reach out to so that this can be investigated further? Thanks in advance!

Dormant space on blacklists, how can I resolve this?
by Matthew Crocker 28 Apr '23

28 Apr '23

Hello, I run Crocker Communications (AS7849) and have ARIN allocations of 161.77.0.0/16 & 66.59.48.0/20. The 66.58.48.0/20 space was used for our datacenter which shutdown a couple years ago. The space has mostly been dormant for the past couple years. I’m now starting to assign 66.59.[55-60].0/24 to a new group of residential FTTH customers. The customers are getting access denied messages from Akamai based websites. What can I do to get Akamai to unblock the 66.59.48.0/20 space. Is there a website I can look to research the reputation of the subnets? They haven’t been used in years so I would expect them to be pretty clean. Thanks -Matt
