VRF Series Article 4 – VRF-lite in a DMVPN Network

As we’ve progressed through the Segmenting Layer 3 Networks with VRFs series, we have continued to build out a network that looks more like what we would see within an enterprise environment. This post takes it one step further and leverages the DMVPN (dynamic multipoint VPN) functionality to extend the network securely over the publicDMVPN Internet. In the examples here, we actually go one step beyond a typical DMVPN and map VRFs to tunnels using the tunnel key. This allows the pci and data VRFs to maintain isolation across the VPN.

One more thing that we will do that isn’t related to the core requirement of segmenting pci from data is leveraging a F-VRF (or front side vrf) on the DMVPN routers to isolate the Internet facing interfaces that connect them to the public cloud. This is my preferred method for DMVPN deployment if I’m not doing split tunnelling (i.e. I am back-hauling all traffic to a central location).

As a prerequisite, I will go ahead and build out the Internet router and the interface on Main that connects to DMVPN-hub.

Harbinger of The Great Internet Wall arrives

By Presidential proclamation, non-U.S. citizens' data is in jeopardy. An executive order by President Trump could hurt a data transfer framework that allows EU citizens’ personal information to be transmitted to the U.S. for processing with the promise that the data would have the same privacy protection in the U.S. as it has in the EU. That’s because a section of the order says, “Agencies shall, to the extent consistent with applicable law, ensure that their privacy policies exclude persons who are not United States citizens or lawful permanent residents from the protections of the Privacy Act regarding personally identifiable information.” To read this article in full or to leave a comment, please click here

Facebook tries to revamp password recovery by supplanting email

Forgot your password? Well, Facebook wants to help you recover your internet account.The company is releasing an open source protocol that will let third-party sites recover user accounts through Facebook.Typically, when people forget their password to a site, they’re forced to answer a security question or send a password reset request to their email. But these methods of account recovery can be vulnerable to hacking, said Facebook security engineer Brad Hill.He recalled a time when he was granted permission to break into an online bank account. To do so, he took advantage of the password reset questions.“It asked me what my favorite color was, and it let me guess as many times as I wanted,” he said Monday, during a presentation at the USENIX Enigma 2017 security conference.To read this article in full or to leave a comment, please click here

Worth Reading: An infrastructure for on demand service profiling

LinkedIn has built hundreds of application services, with thousands of instances running in data centers. Optimizing the performance of these services can dramatically improve user experience and reduce operational costs, and profilers are commonly used to help achieve this. LinkedIn’s On-Demand Profiling infrastructure (“ODP”) is one method we use to identify these optimizations. Profiling is a useful method to improve the performance of services. However, the tooling solutions for profiling don’t have fixed standards, are often decentralized, can be costly, and for a company with a large server footprint such as LinkedIn, are inconvenient to use at best. —Linkedin Engineering Blog

Hyperscalers Ready To Run Barefoot In The Datacenter

Breaking into the switch market is not an easy task, whether you are talking about providing whole switches or just the chips that drive them. But there is always room for innovation, which is why some of the upstarts have a pretty credible chance to shake up networking, which is the last bastion of proprietary within the datacenter.

Barefoot Networks is one of the up-and-coming switch chip makers, with its “Tofino” family of ASICs that, among other things, has circuits and software that allow for the data plane – that part of the device that controls how data moves …
