Even without anycast, an ECMP shouldn't hash on the ECN bits. Doing so will split the flow over multiple paths; avoiding that is the whole point of doing the flow-based hashing in the first place. Anycast "only" turns a potential degradation of TCP performance into a hard failure... :) -Toke

Brocade CER MPLS
by Fawcett, Nick 14 Nov '19

14 Nov '19

I have one CER (let's call him Charlie) that is not able to build an LSP tunnel to another CER. Shows "Currently found no route. Will schedule for retry". Both CER's can ping and traceroute each other. When I had the LSP to the destination router (Snoopy) it adds the LSP and shows UP in status field. Both have the same number of routes in their ospf table. Charlie has other LSP's built to other CER's on the network with productive VLL's and VPLS's. I have removed both lsp's from both Charlie and Snoopy and re-added them and only one Snoopy's LSP comes up. Any ideas? Nick -- Checked by SOPHOS http://www.sophos.com

Apple http/https

Does anyone know if there is an apple cache? Today we noticed that apple store applications and updates are not caching anymore by HTTPs cache servers, and when we checked through DPI, we found that it's been changed into HTTPS! Does anyone know what is going on? Ahmed

I have been recommending to many friends to check in daily at http://irrexplorer.nlnog.net/ to make sure everything is healthy with their prefixes ... Today a colleague reported a problem with an AS58299 ad appearing in "their prefixes". I went look and was showing up on our ASNs too. It took me a while (dããã) to understand what was going on ... Why was irrexplorer showing that prefix in our query? Could anyone reach somebody from OpenFactory/NetShelter/level66network about this? http://lg.ring.nlnog.net/prefix_bgpmap/lg01/ipv6?q=2000::/3 2000::/3 [LEVEL66NETWORK1 11:35:27 from 2a09:11c0::1] * (100/-) [AS58299i] Type: BGP unicast univ BGP.origin: IGP BGP.as_path: 209844 49697 58299 BGP.next_hop: 2a09:11c0::1 BGP.local_pref: 100 BGP.community: (49697,1000) (49697,1007) (49697,2302) BGP.ext_community: (RPKI Origin Validation State: not-found) BGP.large_community: (209844, 100, 13) -- Douglas Fernando Fischer Engº de Controle e Automação

+1 for the IX in Marseille! Cross-connect charges are always the same with IX: you need to buy the pre-cabling (see below) and afterwards you pay CC with MRC: Costs for pre-cabling from your rack to the MMR (NRC): 6 SMD pairs: 2.475,00 Eur 12 SMD pairs: 4.125,00 Eur 24 SMD pairs: 5.960,00 Eur Copper-CC pre-cabling from your rack to the MMR (NRC): 6x UTP/STP RJ45: 1.950,00 Eur 12x UTP/STP RJ45: 2.600,00 Eur 24x UTP/STP RJ45: 3.650,00 Eur Copper CC MRC (same building): 45,00 Eur Copper CC MRC (doesn't matter to which IX building on the IX campus): 85,00 Eur Copper CC MRC (between your own racks): 25,00 Eur SMD CC MRC (same building): 85,00 Eur SMD CC MRC (doesn't matter to which IX building on the IX campus): 85,00 Eur SMD CC MRC (between your own racks): 45,00 Eur I heard something about a raise from 85,00 to 95,00 Eur MRC, but as of yet I didn't have a proof for this.

Disney+ Geolocation Issues
by Mat Perkins 13 Nov '19

13 Nov '19

Hey Everyone, I'm working with 3 ISPs currently who are having Geo Location issues with clients being told they are out of the US. When their IPs are checked via a free Geo IP tool everything is showing up correctly. Anyone have any insight on who Disney+ is using for their GeoLocation services and if anyone here can help out with getting updated to be in the correct location / type of service provider? Mat

Netflix has done a great job deploying OC Appliances. A Netflix user != Amazon, Hulu, etc... At 02:58 PM 12/11/2019, Brian J.
