Multi-port RFC2544/EtherSAM loopback appliance
by Jason Lixfeld 25 May '17

25 May '17

Group, I'm looking for options and opinions on a cost effective, multi-port (6'ish port SFP/SFP+) RFC2544/EtherSAM rack appliance that can act as the remote/loopback for our field installers' portable RFC2544/EtherSAM enabled Exfo test sets. I came across XenaNetworks XenaCompact which looks like it would fit the bill, but I'm sure there are others (save Ixia, Exfo and Fluke, which I'm pretty much excluding by default because I imagine they are likely completely out to lunch on price relative to the extremely simplified feature set we require). Thanks in advance.

Public DNS64
by Tim Durack 01 Jun '16

Anyone know of a reliable public DNS64 service? Would be cool if Google added a Public DNS64 service, then I could point the NAT64 prefix at appropriately placed boxes in my network. Why? Other people are better than me at running DNS resolvers :-) -- Tim:>

Juniper MX Sizing
by Graham Johnston 15 Mar '16

15 Mar '16

I am wondering if anyone can provide their real world experience about sizing Juniper MX routers as it relates to BGP. I am needing a device that has a mix of layer 2 and 3 features, including MPLS, that will have a very low port count requirement that will primarily be used at a remote POP site to connect to the local IX as well as one or two full route transit providers. The MX104 has what I need from a physical standpoint and a data plane standpoint, as well as power consumption figures. My only concern is whether the REs have enough horsepower to churn through the convergence calculations at a rate that operators in this situation would find acceptable. I realize that 'acceptable' is a moving target so I would happily accept feedback from people using them as to how long it takes and their happiness with the product. For those of you that deem the MX104 unacceptable in this kind of role and moved up to the MX240, what RE did you elect to use? Thanks, Graham Johnston Network Planner Westman Communications Group 204.717.2829 johnstong(a)westmancom.com<mailto:johnstong@westmancom.com> P think green; don't print this email.

common checks performed when passing on an IPv4 PA allocation from one end-customer to another
by Martin T 22 Feb '16

22 Feb '16

Hi, when one end-customer has been using for example /24 IPv4 allocation for a while and returns this(for example changes an ISP) to LIR, then are there some good practices before handing out this same /24 to a new customer? I guess LIR should: 1) remove all the DNS PTR records, classless of classful delegations 2) check if some of the IP addresses are in DNSBL(maybe the previous customer was a spammer). Example with 93.184.216.0/24: $ for ip in {0..255}.216.184.93;\ > do for addr in \ > cbl.abuseat.org \ > dnsbl.inps.de \ > no-more-funn.moensted.dk \ > dnsbl.sorbs.net \ > bl.spamcannibal.org \ > bl.spamcop.net \ > psbl.surriel.com \ > dnsrbl.swinog.ch; \ > do dig @8.8.8.8 "$ip"."$addr" +short | grep -q "^127.0.0." && \ > echo "DNSBL-Alarm: $ip is listed on $addr"; done; done $ Anything else? regards, Martin

I'm wondering, why there is no MPLS-TE PCE support for IOS-XE till now?! Should I be getting a 9k/CRS on the edge to implement an automatic tool to build MPLS-TE tunnels! -- Mohamed Kamal Core Network Sr. Engineer

Big day for IPv6 - 1% native penetration
by Tomas Podermanski 05 Jan '16

05 Jan '16

Hi, It seems that today is a "big day" for IPv6. It is the very first time when native IPv6 on google statistics (http://www.google.com/intl/en/ipv6/statistics.html) reached 1%. Some might say it is tremendous success after 16 years of deploying IPv6 :-) T.

VZW - fixed wireless services?
by Ryan Finnesey 20 Jun '15

Does anyone know if Verizon is using its LTE network to offer fixed wireless services? I know Sprint was working on WiMAX hardware with cisco but I assume that was canceled when Sprint started moving to LTE. Cheers Ryan
