RE: Juniper hardware recommendation
by Michael Fiumano 17 May '21

If accurate interface stats are important to you, MX’s don’t support accurate SNMP Interface Utilization, ie they don’t comply with RFC2665/3635, which seems like a fairly basic thing to do but they decided not to, and has been impactful to me in the past. So, any SNMP monitoring of an interface will always show less utilization than what is actually occurring, possibly leading to a false sense of security, or delay in augmentation. Would also affect usage based billing, if you do that. https://www.juniper.net/documentation/us/en/software/junos/network-mgmt/top… For M Series, T Series, and MX Series, the SNMP counters do not count the Ethernet header and frame check sequence (FCS). Therefore, the Ethernet header bytes and the FCS bytes are not included in the following four tables: ifInOctets ifOutOctets ifHCInOctets ifHCOutOctets Thanks, Michael Fiumano *From:* NANOG *On Behalf Of *Mark Tinka *Sent:* Monday, May 10, 2021 10:25 AM *To:* nanog(a)nanog.org *Subject:* Re: Juniper hardware recommendation On 5/10/21 16:19, aaron1(a)gvtc.com wrote: I prefer MX204 over the ACX5048. The ACX5048 can’t add L3 interface to an mpls layer 2 type of service. There are other limitations to the ACX5048 that cause me to want to possibly replace them with MX204’s. But in defense of the ACX5048, we have gotten some good mileage (a few years now) of good resi/busi bb over vrf’s and also carrier ethernet for businesses and lots of cell backhaul… so they are good for that. I’ve heard the ACX5448 was even better. Trio will always provide better features, but come with the price tag to boot. I’m looking at the MX240 for the SCB3E MPC10E hefty with 100 gig ports You might want to look at the MX10003, in that case, as well. We are deploying those for 100Gbps service (customer-facing). Works out cheaper than offering 100Gbps service on the MX240/480/960 for the same task. Mark.

TLD .so Partial Outage?
by Tom Daly 16 May '21

16 May '21

Hello NANOG'ers! I'm observing a near global outage of DNS services from d.nic.so. This appears to be an AfriNIC anycast DNS service. Does anyone have contacts at AfriNIC for their DNS systems available? e.nic.so seems to be responding (hosted behind PCH, thanks Woody!). Tom -- Tom Daly tjd(a)q7.io

Anyone from REACH IRR on this list?

Dear REACH admins, >From the email address in Merit’s IRR Directory [Reference: http://www.irr.net/docs/list.html#REACH ], I contacted you at dbadmin(a)telstraglobal.net regarding taking-down a fake IRR entry of my prefix [original email attached below], but got the response from Gmail saying that it cannot contact your email server. Please kindly consider my request. Best Regards, Pirawat. ---------- Forwarded message --------- From: Pirawat WATANAPONGSE <pirawat.w(a)ku.th> Date: Thu, May 13, 2021 at 3:24 PM Subject: Request: fake IRR entry take-down To: <dbadmin(a)telstraglobal.net> To whom it may concern, We---at Kasetsart University, Thailand [Reference: https://rdap-web.apnic.net/autnum/AS9411]---are in the process of strengthening our routing security against (BGP) Route Hijacking. We have already registered all of our prefixes with the APNIC RPKI Trust Anchor. We present the following URL as an authentication of prefixes ‘ownership’. [Reference: https://rpki.cloudflare.com/?view=explorer&validateRoute=9411_&asn=9411&ext… ] However, your database is currently announcing 1 fake entry incorrectly listing AS4750 as the origin of *our* 158.108.0.0/16 netblock. [Reference: https://bgp.he.net/net/158.108.0.0/16#_irr] That fake entry represents a security threat to our network. Any AS that implements IRR-Only Route Filtering will obviously trust your database and thus will divert our traffic somewhere else. We therefore humbly request that you take down that fake entry. If you have any questions, please feel free to email me using the addresses in the signature section. Thank you in advance for your help.

Juniper hardware recommendation
by Javier Gutierrez Guerra 14 May '21

14 May '21

Hi, Just out of curiosity, what would you recommend using for a core router/switch from Juniper? MX208,480,10K Datasheets show them all as very nice and powerful devices (although they do use a lot of rack space and side to side airflow is painful) but I’m just wondering here what most people use and how good or bad of an experience you have with it 😊 Thanks, Javier Gutierrez Guerra Network Analyst CCNA R&S, JNCIA Westman Communications Group Phone: 204-717-2827 Email: guerraj(a)westmancom.com<mailto:guerraj@westmancom.com> [WCG_Corp_Logo_horiz_cFullcolorHR]<http://westmancom.com/personal/> [cisco-certified-network-associate-routing-and-switching-ccna-routing-and-switching]

Shaw Cable (AS6327) traffic Engineering communities
by Christopher Munz-Michielin 12 May '21

12 May '21

Hey all, Anyone on the list familiar with traffic engineering for Shaw (AS6327)? I support an anycast DNS network and one of our upstream networks has Shaw in their blend, which gives us great access to Shaw's customers (desired) but unfortunately also results in Shaw announcing our prefixes out all their IX links around the world, pulling a bunch of traffic across the continent unnecessarily. If anyone is familiar with traffic engineering towards Shaw and could contact me on or off list it would be appreciated. Regards, Christopher Munz-Michielin

juniper qfx5120-ym - curvature - infinera optic issues
by JASON BOTHE 10 May '21

10 May '21

NANOG Fam This is a rather interesting issue to see if anyone has ran across this with a Curvature branded 10 or 100G LR optic in a Juniper QFX facing an Infinera wave. What we’ve noticed is migrating from MX 204 to a new QFX 5120-YM that has an Infinera as the handoff, the circuit just bounces constantly. Disabling ALS will steady the light but the interface will continue to bounce. What does work is migrating an interface that happens to hang off an ADVA R7; no problem. Circuit even works in a hybrid mode where one side is adva and the other is Infinera, as long as the Infinera side is connected to an MX :-) Anyhow, curious to know if anyone else has experienced anything similar. Our next step is to test tomorrow with OEM optics and see if the trouble follows. J~
