Level3 routing issues today?
by Nick Ellermann 12 Feb '15

12 Feb '15

Has anyone else having issues with Level3 routing traffic to the Godaddy ASN? Since about 1PM Eastern today we have had numerous customers claiming their internet was down, when it has only been a few websites they couldn't reach. It's been up and down on My FiOS link some today as well. But right Verizon seems fine they are hitting Qwest before Godaddy for where I live in VA. >From our network. (AS30259) we are going out (AS3356) and for the most part we reach our peering router in Northern Va, the we see 4.34.191.254 before time outs forever. Could this be a regional Level3 issues? Anyone from Level3 or GoDaddy that could comment? We have had an open Level3 ticket since about 4PM Eastern.

11 Feb '15

Hello, I was looking for feedback on the following question:- When connecting two MM SFP/SFP+/XFP 's together...(short range). What should be the best practice receive power range ? Is it true that if the rx power is higher than (x?) then it shortens the life of the optics ? (assumption being made here is that MAX Rx Power is not being exceed as per the spec sheets of the optics) Regards Faisal Imtiaz Snappy Internet & Telecom 7266 SW 48 Street Miami, FL 33155 Tel: 305 663 5518 x 232 Help-desk: (305)663-5518 Option 2 or Email: Support(a)Snappytelecom.net

Comcast Static IP Changed With New Modem?
by Justin Krejci 11 Feb '15

11 Feb '15

Has anyone run into the situation where their static IP address from Comcast (on the business class cable modem Internet service) was changed when the modem was replaced? We have a remote site that uses Comcast as a backup Internet connection and when we went to use it recently our VPN tunnel would not establish. After working with the Comcast support group we discovered Comcast changed our static IP address. I am working through trying to figure out the when and the why with Comcast still and suspect it was changed when the modem was replaced back in December. The modem was replaced by Comcast as our previous modem was apparently EOL'ed. We're now setting up additional monitoring to verify the accessibility of our remote site via the Comcast connection so we don't have any future uh-ohs when we need to use our backup connection and it too is not fully functional. TIA, -Justin

Any recommendations for FXS/FXO hardware with Cisco Unified CME
by Joel M Snyder 11 Feb '15

11 Feb '15

Folks: Since a lot of NSPs are also in the VoIP business, I was wondering if anyone has specific recommendations for low-density (2-8 ports) FXS/FXO hardware that they are using with Cisco PBX devices. (And I guess T1/E1 as well.) I know that typical IOS boxes can take modules/interfaces/whatever to handle FXS/FXO/T1/E1, but I'm trying to put some electrical distance between the Cisco PBX and the phone company to keep environmental problems (lightning, mostly) from blowing up the PBX. Cisco themselves seem to have cancelled almost all of their low-end hardware, leaving us with Sipura/Linksys. I have had good results with Audiocodes+Asterisk, but not in the Cisco PBX environment. Does anyone have boots-on-the-ground knowledge of good analog gateway choices that play very nicely with Cisco PBX? jms -- Joel M Snyder, 1404 East Lind Road, Tucson, AZ, 85719 Senior Partner, Opus One Phone: +1 520 324 0494 jms(a)Opus1.COM http://www.opus1.com/jms

IPv6 allocation plan, security, and 6-to-4 conversion
by Eric Louie 10 Feb '15

10 Feb '15

I'm putting together my first IPv6 allocation plan. The general layout: /48 for customers universally and uniformly /38 for larger regions on an even (/37) boundary /39 for smaller regions on an even (/38) boundary A few /48's for "internal use" to allow us to monitor and maintain systems. For security sake, do I need (am I better off) to "reserve" a "management block" (/39, /40, /41 or something of that nature) that does NOT get advertised into BGP to my upstreams, and use that for my device management and monitoring address space? In other words, make a small "private" address space for management? What are folks doing around that? If I have to do 6-to-4 conversion, is there any way to do that with multiple diverse ISP connections, or am I "restricted" to using one entry/exit point? (If that's true, do I need to allocate a separate block of addresses that would be designated "6 to 4" so they'd always be routed out that one entry/exit point?)
