KEA DHCPv6 HA - help with failover
by Aaron Gould 11 Sep '25

11 Sep '25

Anybody doing KEA DHCPv6 HA dual servers? We tested an outage scenario of bringing down KEA service on one of the servers, but the other server didn't seem to be able to service new DHCPv6 requests (or handle the existing ones, that were previously given out by the now-downed server). -- -Aaron

So am I just excitable?
by michael brooks - ESC 09 Sep '25

09 Sep '25

I have been watching the "Weekly Global IPv4 Routing Table Report" for a while now, and have been itching to see the *BGP routing table entries examined line* hit 1M. Now, perhaps I am naive, I am assuming that line correlates to the actual number of routing table entries, true? Am I the only one a bit excited to see this? Is this a non-event? michael brooks Network/Systems Administrator IV Adams 12 Five Star Schools michael.brooks(a)adams12.org :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: "flying is learning how to throw yourself at the ground and miss" -- <http://www.adams12.org> -- This is a staff email account managed by Adams 12 Five Star Schools.

control characters in BGP shutdown communication(RFC 9003) messages and NETCONF
by Martin Tonusoo 08 Sep '25

08 Sep '25

Hi. Meta(AS 32934) recently sent a cease NOTIFICATION message to its neighbors on AMS-IX and Piter-IX which had a "<0b>maintenance" string on the RFC 9003 "Shutdown Communication" field. In other words, the "Shutdown Communication" field contained "0b 6d 61 69 6e 74 65 6e 61 6e 63 65". At least on Junos(tested with versions 21.4R3-S3.4, 23.2R2-S4.5 and 25.2R1.9), calling the "get-bgp-summary-information" or "get-bgp-neighbor-information" RPCs using NETCONF returns the string containing the control character and this in turn means that libraries parsing the XML fail as 0x0b(vertical tab) is not in the allowed character range of XML 1.0: https://www.w3.org/TR/xml/#charsets Who is to blame here? Junos, for returning invalid characters in its NETCONF response? Martin

Canada mandates for Telecom outage reporting Nov. 4
by Sean Donelan 08 Sep '25

08 Sep '25

Canada's telecommunications regulator is mandating service providers to notify it and other government authorities within two hours when they experience a major network outage. The requirements take effect permanently on Nov. 4, 2025 Providers must give a comprehensive post-outage report to the CRTC within 30 days of restoring services after a major service outage. These reports must explain the reasons for the outage and the steps taken to prevent similar outages in the future. https://www.cbc.ca/news/business/telecom-outages-crtc-rules-1.7625283 https://www.canada.ca/en/radio-television-telecommunications/news/2025/09/b…

Spoofer Report for NANOG for Aug 2025
by CAIDA Spoofer Project 08 Sep '25

08 Sep '25

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.
