Re: Must have ISP Open Source & tools
I don't know if the areas have been evaluated or not. I would hyperconverge and virtualize as much as possible. I would attempt MPLS with a VRF gateway. Money will probably be an issue so hosting VoIP and Content services may be good. Are you using wireless, cable, satellite as the backhaul? If this is completely Greenfield, then evaluating a location, finding relay sites and etc should be done 1st.

In some cases, the motivation for these requirements is fueled by trying to outsmart your competitors. I just don't know of a reliable, contractual way that you can use QoS to say your DIA or IP Transit service is better than that of your competitor. Mark.
Re: [nanog] Cisco GLBP/HSRP question -- Has it ever been dis
If you're looking for vendor neutral FHRP, VRRP has RFC documentation. GLBP and HSRP are Cisco proprietary protocols and are protected information other than the study material and how too out there.

I'm a routing guy mainly working with ISIS/BGP for my company in our core space. I have an opportunity to get involve with our L2 DWDM network. We are a Cisco shop using NCS2K as DWDM nodes. But before jump into learning the NCS specific stuff, I would like to take a vendor neutral training course in Optical fiber testing with OSA/OTDR, OTN, DWDM signaling, OSNR/dispersionetc. I think this will help me understand how to build out a DWDM network from ground up. I'm hoping someone I could get into designing network for my company. Thanks in advance,James
Re: Feedback - SBC Vendors.

We are going to pass the SIP traffic off to a larger number of SIP providers. I would like to get some feedback from the group on SBC vendors. I have two options for vendors Ribbon or AudioCodes. I am leaning towards a software based SBC over an appliance. Would be helpful to get the other members feedback on Ribbon or AudioCodes deployments within their networks. Cheers Ryan

Nearly 13 years ago I have attempted to start Puerto rico Internet exchange in San Juan. I have lived there over 5 years and i just wanted to really watch videos faster. The project somewhat died when i moved to LA but now there are few interested party to start an internet exchange in Puerto rico. The jsland historically had one of the slowest broadband/internet services which seemed to have improved in recent years however as of 2017 there still is not an IX in Puerto rico. We , 3-4 internet engineers (on island and remote) , want to look into relaunch of this IX and hopefully find a way to keep local traffic exchanged at high speeds and low cost. We need expertise, and people who want to help any way they can. We are trying to make this IX a not-for-profit one and we are looking at opeeating models to adapt which has worked incredibly well like Seattle IX. We are hoping the relaunch to happen sometime in 2018. Thanks in advance hope to share more info and traffic data sometime , soon. Watch this space! Mehmet
Re: how to deal with port scan and brute force attack from AS 8075 ?
You could use Shields Up to view your vulnerabilities... obvious ones, and remedy...

(And if you can't do it at your border because you sub-allocate address space to customers, figure out how to use iptables or similar to block it on the target hosts, or only apply the ACL for your own subnets). If you have a *legitimate* business case for needing to SSH in from outside, there are fine products such as OpenVPN (and not-so-fine like the one we have in production - although it's mostly usable too, and achieves the goal of presenting you as being inside our corporate address space) Also, move your SSH service to some port other than 22, and consider putting 'Password Authentication no/PubKeyAuthentication yes' in your sshd_config. I admit never understanding why people run their systems in a low-hanging fruit configuration, and then are surprised that miscreants go looking for low hanging fruit. (For the record, our border routers drop inbound SYN on port 22 on *both* ipv4 and ipv6 address spaces. It's amazing how few brute force attempts we see on our servers... :)
