I know that some IXPs use Nexus, Brocade, Force10 but I don't personally have experience with these switches. It would be great if you can share your experience and recommendations. There are so many options that I don't know if it makes sense to start with a modular switch (usually expensive because the backplane, dual dc, dual CPU, etc) or start with a 1RU high density switch that support new protocols like Trill and that supposedly allow you to create Ethernet Fabric/Clusters. The requirements are simple, 1G/10G ports for exchange participants, 40G/100G for uplinks between switches and flow support for statistics and traffic analysis. Thank you and have a great day.

DDOS solution recommendation
by Manuel Marín 13 Jan '15

13 Jan '15

Nanog group I was wondering what are are using for DDOS protection in your networks. We are currently evaluating different options (Arbor, Radware, NSFocus, RioRey) and I would like to know if someone is using the cloud based solutions/scrubbing centers like Imperva, Prolexic, etc and what are the advantages/disadvantages of using a cloud base vs an on-premise solution. It would be great if you can share your experience on this matter. Thank you

Google's Safe Browsing Alerts for Network Administrators
by Frank Bulk 13 Jan '15

13 Jan '15

I want to make this forum aware of Google's "Safe Browsing Alerts for Network Administrators" (https://www.google.com/safebrowsing/alerts/) I've had a link to their diagnostic page for several years (https://www.google.com/safebrowsing/diagnostic?site=AS:####&hl=it-it, where #### is your ASN), but I didn't know that Google actually had a way to alert ASN owners of new incidents. I checked NANOG's archive and haven't ever seen it mentioned, so I thought there might be more like me that weren't aware. And while I'm on the subject, I want to make people aware of somewhat related service by ShadowServer (https://www.shadowserver.org/wiki/pmwiki.php/Involve/GetReportsOnYourNetwor k). Frank

Root and ARPA DNSSEC operational message - signature validity period
by Wessels, Duane 12 Jan '15

12 Jan '15

DNSSEC signatures in the Root and ARPA zones were initially given a validity period of 7 days. The validity period is being increased to 10 days. Both the Root and ARPA zones publish their NS RRsets with a TTL of 6 days. A signature validity period of 7 days means that a root server instance that is not updated within 24 hours may return NS RRset responses whose TTL exceeds the signature validity. This could cause problems for validating recursive name servers that forward queries through non-validators. A longer signature validity provides a longer buffer in the distribution of these zones. Note that we are not aware of any cases where the 7 day signature validity period has caused problems for DNSSEC validators. This is a precautionary measure. As of today, the zones now have the increased validity period. Please feel free to contact us with concerns or questions.

command that can display routes containing AS loops
by Song Li 12 Jan '15

12 Jan '15

Hi everyone, I am curious about the AS loops in the AS-path. I think there should be a very, very few received BGP routes that contain the local AS#. But because such routes will be dropped and not installed in Loc-RIB, I want to know if there is a command that can display the dropped routes containing AS loops (in cisco or juniper router). Does anybody know? Thanks!
