Best TAC Services from Equipment Vendors
by Pascal Masha 14 Mar '24

14 Mar '24

Thought about it but so far I believe companies from China provide better and fast TAC responses to their customers than the likes of Cisco and perhaps that’s why some companies(where there are no restrictions)prefer them for critical services. For a short period in TAC call you can have over 10 R&D engineers and solutions provided in a matter of hours even if it involves software changes.. while these other companies even before you get in a call with a TAC engineer it’s hours and when they join you hear something like “my shift ended 15 minutes ago, hold let me look for another engineer”. WHY? Thoughts

Value of linux net.ipv6.route.max_size
by Willy Manga 14 Mar '24

14 Mar '24

Hi, I recently noticed an issue with some routers complaining with that message: "kernel: Route cache is full: consider increasing sysctl net.ipv6.route.max_size." These routers are running FRR on Debian 12 , kernel 6.1.0-17-amd64. They are receiving full routing table and routes are inserted into the kernel routing table. I saw a similar error here [1] and it leads me to [2] as well but I should admit I did not read everything. I did not dive into the details of the two links but for now , I want to increase that value (and find the source of that error). The current value of net.ipv6.route.max_size is: 4096 . I guess it's the default on at least that kernel. For reference net.ipv4.route.max_size=2147483647 . Of course, we cannot correlate the two but I was wondering, what either people are using or what might be a reasonable value for the IPv6 counterpart. 1. https://bugzilla.redhat.com/show_bug.cgi?id=1813691 2. https://lore.kernel.org/netdev/e022d597-302d-c061-0830-6ed20aa61e56@qtmlabs… -- Willy Manga

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within usa, can.
