DWDM Mux/Demux using 40G Optics
by Colton Conor 26 Jul '17

26 Jul '17

We are building a 40G metro ring using 40-Gigabit Ethernet QSFP+ Transceivers. Specifically, we are using Juniper JNP-QSFP-40G-LR4. This is a QSFP+ Transceiver with a LC duplex head. We only have one pair of single mode dark fibers around the ring. Our distance between nodes around the ring are all less than 10KM, so we can use standard optics. We go out of one JNP-QSFP-40G-LR4 and into another JNP-QSFP-40G-LR4. There are no passive muxes involved. This is working great for 40G. My understanding is a JNP-QSFP-40G-LR4 is really a transceiver with a CWDM mux built into it. The spec sheet shows it sends 4 10G channels: https://www.juniper.net/documentation/en_US/release-independent/junos/topic… Lane wavelength Lane 0–1264.5 nm through 1277.5 nm Lane 1–1284.5 nm through 1297.5 nm Lane 2–1304.5 nm through 1317.5 nm Lane 3–1324.5 nm through 1337.5 nm This setup is working fine, but now we want to do more than 40G around the ring. To my knowledge there are no other 40G QSFP+ transceivers that use four other channel/lanes than the ones already being used, so they only way to go higher than 40G is to stack 10G or 100G channels ontop of the fiber pair using a passive mux. 100G is too expensive for the time being, so we are looking to add 10G channels to a ring that already have one 40G channel using the QSFP+. I was reading this tutorial, and it mentions "there is a 1310 nm port integrated in a 40 channels DWDM Mux/Demux system. The 1310nm added port is a Wide Band Optic port (WBO) added to other specific DWDM wavelengths in a module. When we run out of all channels in a DWDM Mux/Demux system, we can add the extra optics via this 1310nm port." http://www.fs.com/upgrade-to-500g-with-40ch-dwdm-mux-demux-system-aid-493.h… What I can't seem to understand is they are mentioning that this 1310 port can pass QSFP+ signals, so it sounds like its really a 1270nm through 1330nm port? Is this what they mean by Wide Band Optic port (WBO)? We don't need 40 10G channels plus a 40G for a total of 440G. More than likely we are looking at a 8 channel mux/demux, and 1 40G port for a total of 120G. I don't care if we do CWDM vs DWDM, but I assume it will be hard to find a CWDM mux that has one LC dupluex input for 1270nm through 1330nm channels? Maybe I should just ditch the 40G QSFP+ optics and use all 10G optics, but the switches I am using have 48 10G SFP+ ports and 6 QSFP+ ports built in. I know there are 40G breakout cables, but the whole point of 40G is to aggregate VLAN/circuits. Has anyone done this before?

10G MetroE 1-2U Switch
by Erik Sundberg 13 Jul '17

13 Jul '17

Hey Nanog, Looking for a new metroE Edge switch that has more that 10x 10G ports. I am having a hard time finding anything worthwhile without buying a full blown ASR9K Chassis or another vendor's chassis. Requirements MEF compliant 1-2U small foot print 10G Ports will be used for ENNI's and UNI Ports Prefer MPLS support for L2VPN's (EoMPLS and VPLS) QOS per Sub interface\vlan on a ENNI Cost effect 10G Ports 100G Not required Looking at the ASR920's - Great box for 1G but not enough 10G Ports Only 4 NCS5001/NCS5501 - New\unproven\probably buggy, Lacking some features & QOS issues :/ ASR900 - Looks good, but was hoping for a smaller foot print. If I remember right the 8x10G Cards can't go in every slot. Any other platforms I should be looking at? Ciena, Brocade, Juniper? Thanks in advance! -Erik ________________________________ CONFIDENTIALITY NOTICE: This e-mail transmission, and any documents, files or previous e-mail messages attached to it may contain confidential information that is legally privileged.

IPv4 Hijacking For Idiots
by Ronald F. Guilmette 03 Jul '17

03 Jul '17

The more I know, the less I understand. Maybe some of you kind folks can help. Please explain for me the following scenario, and how this all actually works in practice. Let's say that you're a malevolent Bad Actor and all you want to do is to get hold of some ASN that nobody is watching too closely, and then use that to announce some routes to some IPv4 space that nobody is watching too closely, so that you can then parcel out that IP space to your snowshoe spammer pals... at least until somebody gets wise. OK, so you pull down a copy of, say, the RIPE WHOIS database, and you programatically walk your way through it, looking for contact email addresses on ASN records where the domain of the contact email address has become unregistered. Say for example the one for AS34991. So then you re-register that contact domain, fresh, and then you start telling all of your friends and enemies that you -are- AS34991. That part seems simple enough, and indeed, I've seen -this- part of the movie several times before. However once you have stepped into the identity of the former owners of the ASN, if you then want to actually proceed to -announce- some routes, and actually ave those routes make it out onto the Internet generally, then you still have to -peer- with somebody, right? So, I guess then, if you're clever, you look and see who the ASN you've just successfully hijacked has historically peered with, and then you somehow arrange to send route announcements to those guys, right? (I'm talking about AS206776 and AS57344 here, BTW.) But see, this is where I get lost. I mean how do you push your route announcements to these guys? (I don't actually know that much about how BGP actually works in practice, so please bear with me.) How do you know what IP address to send your announcements to? And if you are going to push your route announcements out to, say, the specific routers that are run by AS206776 and AS57344, i.e. the ones that will send your desired route announcements out to the rest of the Internet... well.. how do you find out the IP addresses of those routers on those other networks? Do you call up the NOCs at those other networks and do a bit of social engineering on them to find out the IP addresses you need to send to? And can you just send BGP messages to the routers on those other networks without -any- authentication or anything and have those routers just blindly accept them -and- relay them on to the whole rest of the Internet?? I've read article after article after article bemoanging the fact that "BGP isn't secure", but now I'm starting to wonder just how massively and unbelieveably unsecure it actually is. I mean would these routers being run by AS206776 and AS57344 just blindly accept -any- route announcements sent to them from literally -any- IP address? (That seems positively looney tunes to me! I mean things can't really be THAT colossally and unbelievably stupid, can they?) Thanks in advance for any enlightenment. Regards, rfg P.S. It would appear to be the case that since some time in April of this year the "Bulgarian" network, AS34991, had evinced a rather sudden and pronounced affinity for various portion of the IPv4 address space nominally associated with the nation of Columbia, including at least five /24 blocks within 168.176.0.0/16 which, from where I am sitting, would appear to belong to the National University of Columbia. Oh well. They apparently haven't been missing those five gaping holes in their /16 since the time the more specifics started showing up in April. And anyway, so far it looks like the new owners of AS34991 haven't actually sub-leased any of those /24s to any spammers yet. Only the 190.90.88.0/24 block seems to be filled, wall-to-all, with snowshoe spammers so far.

Transit Providers in Bracknell, UK
by Gary T. Giesen 03 Jul '17

03 Jul '17

Can anyone recommend a transit provider in Bracknell, UK? Not too picky on requirements, but IPv6 is a must; RTBH and good peering are a very good to have. We're looking to replace one of our current providers (Virgin Media - AS5089). I have no problem naming them as they treat prefix list updates like service changes (and charge £250 for the privilege). We gave in and paid it and and 2 weeks later they have still not processed the change. Cheers, GTG

Fwd: Bonus support for Action for Children

excuse the subject, relevant as IT techies like this. > > Bonus support for Action for Children > A BT senior manager is donating half of his bonus to Action for Children’s Byte Night North West event and encouraging others to do the same. > Colin Johnston is an IT technical manager who has supported Action for Children for several years. This year he and hundreds of other executives will be sleeping out for a night on 6 October as part of the charity’s annual Byte Night event. As well as raising money by taking part in this, Colin has decided to also donate 50% of his bonus payment (£2,482.00 / 2 = £1241(donation amount)) this year to Action for Children. > Colin said, “Being involved for a while with Action for Children, I’ve got to know about the amazing work they do with children and young people and families. I’m happy to be in a position where I can help support their services by fundraising and donating. If people can’t take part in Byte Night then they can still help out by donating what they can – if other executives decided to also give half of their bonus to Action for Children, it would be a simple but really effective way of helping young people to have a brighter future.” > > Byte Night is Action for Children's biggest annual fundraiser; a national ‘sleep-out’ event. Each year, hundreds of like-minded people from the technology and business arena give up their beds for one night to help change the lives of vulnerable young people. It all began in 1998 when 30 individuals slept out in London and raised £35,000. Since then Byte Night has grown to 10 UK locations and over 1,200 people slept out in 2016. Byte Night is one of the UK’s top 17 mass participation charity events and is the largest charity sleep-out having raised over £9.6 million since the first event. Byte Night is celebrating its 20th anniversary this year and its fifth year in the North West. > Colin is a board member of the North West Byte Night event. > BT Volunteering is a very worthwhile endeavour. > > See mydonate page linked to Byte Night https://mydonate.bt.com/fundraisers/colinjohnston1 <https://mydonate.bt.com/fundraisers/colinjohnston1> > > For more information go to www.bytenight.org.uk <http://www.bytenight.org.uk/> or to donate Text Byte17 and the amount to 70070. > > Colin > > Colin Johnston <https://myprofile.bt.com/Person.aspx?accountname=IUSER%5C600969844> > IT Support Senior Professional, Core IT Infrastructure > BT Technology Service & Operations <https://intra.bt.com/bt/tso/Pages/index.aspx> | Tel: 01313001324 <tel:01313001324> | MyProfile <https://myprofile.bt.com/Person.aspx?accountname=IUSER%5C600969844> | colin.johnstone(a)bt.com <mailto:colin.johnstone@bt.com> | http://fixit.bt.com/ <http://fixit.bt.com/> > > BT Group plc Registered office: 81 Newgate Street London EC1A 7AJ.

Point 2 point IPs between ASes
by Krunal Shah 30 Jun '17

30 Jun '17

Hello, What subnet mask you are people using for point to point IPs between two ASes? Specially with IPv6, We have a transit provider who wants us to use /64 which does not make sense for this purpose. isn’t it recommended to use /127 as per RFC 6164 like /30 and /31 are common for IPv4. I was thinking, if someone is using RFC7404 for point to point IP between two ASes and establish BGP over link local addresses. This way you have your own IP space on your router and transit provider does not have to allocate IP space for point to point interface between two ASes. In traceroutes you would see only loopback IP address with GUA assigned from your allocated routable address space. Remotely DDoS to this link isn’t possible this way. Thoughts?
