cisco nexus 9000 cctrl ERROR
by Scott Weeks 17 Jan '20

17 Jan '20

I don't have a login to cisco to find out what this is and I'm having trouble finding anything about it in search engines that doesn't require a login to cisco. I guess they only want certain folks to know about it... :( Does anyone know anything about this and can explain it to me? If not, I'll go join cisco-nsp and ask there. %KERN-3-SYSTEM_MSG: [65292299.903992] - kernel %KERN-3-SYSTEM_MSG: [66730914.839059] cctrl ERROR: cctrl_wait_for_pmbio_busy_status NACK error tmp_data 3b19600 - kernel %KERN-3-SYSTEM_MSG: [67511639.312284] cctrl ERROR: cctrl_wait_for_pmbio_busy_status NACK error tmp_data 1b18100 - kernel Those last numbers after tmp_data repeat over and over. Thanks! scott

De-bogonising 2a10::/12
by Emile Aben 17 Jan '20

17 Jan '20

Dear colleagues, We have now started de-bogonising 2a10::/12! As part of this, we are announcing a couple of prefixes out of 2a10::/12 from AS12654 (RIPE's Routing Information Service, RIS). Pingable targets have been configured in these prefixes, and we invite network operators to test for themselves whether this address space is reachable. The simplest way to do this would be to perform a ping6 to 2a10:4::1 . Using RIPE Atlas and RIS, we will also be carrying out our own tests in order to investigate connectivity and filtering for this address space. We plan to share our results with the RIPE community via RIPE Labs within the next few days. For those who want to do other testing, beyond the basic test described above, we have a total of 8 targets available for this, with 2 different prefix lengths and all variations of having ROUTE objects in the RIPE DB and/or ROAs. 2a10:3:4::1 /48 ROUTE object + ROA 2a10:3:5::1 /48 no ROUTE object + ROA 2a10:3:6::1 /48 ROUTE object + no ROA 2a10:3:7::1 /48 no ROUTE object + no ROA 2a10:4::1 /32 ROUTE object + ROA 2a10:5::1 /32 no ROUTE object + ROA 2a10:6::1 /32 ROUTE object + no ROA 2a10:7::1 /32 no ROUTE object + no ROA Kind regards, Emile Aben RIPE NCC

GPS may be jammed for several hours per day in the SE US Jan 16-24
by Marshall Eubanks 17 Jan '20

17 Jan '20

I thought this might be relevant to many: GPS reception may be unavailable or unreliable over a large portion of the southeastern states and the Caribbean during offshore military exercises scheduled between January 16 and 24. The FAA has posted a flight advisory for the exercises that will require jamming of GPS signals for periods of several hours each day of the event. Navigation guidance, ADS-B, and other services associated with GPS could be affected for up to 400 nautical miles at Flight Level 400, down to a radius of 180 nm at 50 feet above the ground. https://www.aopa.org/news-and-media/all-news/2020/january/14/gps-jamming-ex… Regards Marshall Eubanks

IPv6 Prefix Delegation to customers.
by Brandon Price 17 Jan '20

17 Jan '20

Hey Nanog, I am in the process of building out a FTTH proof of concept, and I would really like to offer each of my customers a /48 of IPv6. I've been able to announce my /32 to my upstreams, dual-stack all of my internal infrastructure no-problem, build v6 recursive name servers, etc. This was fairly straight-forward. Where I am struggling is the Prefix Delegation part. How are most folks getting the PD subnets into their IGPs? In my environment I don't run the DHCP server process on the router that is directly connected to the clients. I have seen documentation that cisco and juniper DHCPv6 processes are smart enough to insert that prefix into the routing table when they hand it out, but how is this handled in an environment with a central DHCP server? I do not currently run any PPPOE in my environment and I don't use RADIUS for the subscriber management. I would really just like to stick to DHCP ideally. If anyone has any pointers, I would appreciate it.
