MikroTik – RouterOSv7 first look – VxLAN

VxLAN support added in 7.0beta5

MikroTik announced VxLAN support on Valentine’s Day (Feb 14th) of 2020.

This is a significant feature addition for RouterOSv7 as it will pave the way for a number of other additions like EVPN in BGP.

It will also give MikroTik the ability to appeal to enterprises and data centers that might need cost-effective VxLAN capable devices.

Service Providers are also moving towards VxLAN as a future replacement for VPLS so this is helpful for that market as well.

Implementation

The initial release of VxLAN is based on unicast and multicast to deliver Layer 2 frames.

As there is no EVPN support, the VTEPs must be manually configured for each endpoint in a full mesh configuration.

The VxLAN interface can then be bridged to a physical ethernet port or VLAN interface to deliver the traffic to the end host.

Lab Example

Here is an overview lab in EVE-NG with a basic setup using 3 linux servers on the same 10.1.1.0/24 subnet which is carried as an overlay by VxLAN.

VxLAN reachability for VTEPs is acheived with OSPFv2 and loopback addresses.

Real-time DDoS mitigation using BGP RTBH and FlowSpec

DDoS Protect is a recently released open source application running on the sFlow-RT real-time analytics engine. The software uses streaming analytics to rapidly detect and characterize DDoS flood attacks and automatically applies BGP remote triggered black hole (RTBH) and/or FlowSpec controls to mitigate their impact. The total time to detect and mitigate an attack is in the order of a second.

The combination of multi-vendor standard telemetry (sFlow) and control (BGP FlowSpec) provide the real-time visibility and control needed to quickly and automatically adapt the network to address a range of challenging problems, including: DDoS, traffic engineering, and security.

Solutions are deployable today: Arista BGP FlowSpec describes the recent addition of BGP FlowSpec support to Arista EOS (EOS has long supported sFlow), and sFlow available on Juniper MX series routers describes the release of sFlow support on Juniper MX routers (which have long had BGP FlowSpec support). This article demonstrates DDoS mitigation using Arista EOS. Similar configurations should work with any router that supports sFlow and BGP FlowSpec.
The diagram shows a typical deployment scenario in which an instance of sFlow-RT (running the DDoS Protect application) receives sFlow from the site router (ce-router). A  Continue reading

The Softer Side Of Exascale

When talking about high-end HPC systems in the world, much of the attention often is paid to the massive supercomputers that are being developed by the likes of system makers Cray (now part of Hewlett Packard Enterprise and the main contractor on two exascale systems), Fujitsu, Atos, IBM, and others along with component makers Intel (which is a primary contractor on one exascale system), AMD, and Nvidia. …

Heavy Networking 502: Get Off My VLAN! Old Network Engineers On What New Engineers Should Know

As more abstractions and automation layers creep into the network, are network engineers losing their grasp on core fundamentals? Three grumpy old network engineers ponder this question, talk about how we got here, and what can be done about it. Our guests are Chris Young and Ivan Pepelnjak.

Member News: Internet Society Chapters Focus on Security

Security on your mind: The Internet Society’s Chapter in Benin recently hosted a conference focused on online security and on connectivity issues. Much of the discussion focused on instability of connections in the country, with participants concerned about degraded connections. Participants also talked about limited coverage for mobile services. On the topic of security, speakers urged Internet users to regularly change their passwords, avoid default passwords, and prevent third-party apps from connecting to the services they use.

Secure messages: The Israeli Chapter has focused on the security of messaging and social media apps recently. The Chapter recently posted a guide on how to prevent Instagram accounts from being hacked and a guide on how users can protect their privacy on the Tik Tok messaging app.

Privacy for the young ones: Meanwhile, the Chapter in Portugal, working with the Kids Safe on the Net project, has launched an initiative to improve awareness among Portuguese youth about the importance of online privacy and how they can maintain their privacy.

Good privacy: The Netherlands Chapter recently gave its support to the Good ID initiative, an approach to identity management that prioritizes data privacy and security. Good ID aims to give Internet users Continue reading

Fast Friday – Networking Field Day 22 Thoughts

Since I’m on the road again at Networking Field Day this week, I have had some great conversations with the delegates and presenters. A few stray thoughts that may develop into full blown blog posts at some point, but I figured I could get some of them out here for some quick entertainment.

  • The startup model means flexibility. That also means you can think about problems in a new light. So it would follow that you get to develop some new idea without a mountain of technical debt. Things like archaic platforms and crusty old user interfaces. You’d be surprised the amount of stuff that gets carried forward as technical debt.
  • Integrating products isn’t easy. Even if you think you’ve got the right slot for your newest acquisition you may find it isn’t the best fit overall. Or, even better, you may find a synergy you didn’t know existed because of a forgotten tool. Very rarely does anything just neatly fit into all your plans.
  • The more guest Wi-Fi I have to register for, the more I long for the days of Passport and OpenRoaming. If you already know who I am, why oh why must I continually register. Who Continue reading

Podcast: BGP in Public Cloud Revisited

After my response to the BGP is a hot mess topic, Corey Quinn graciously invited me to discuss BGP issues on his podcast. It took us a long while to set it up, but we eventually got there… and the results were published last week. Hope you’ll enjoy our chat.

I talked about (lack of) network security in How Networks Really Work webinar. I’ll cover similar topics in the Upcoming Internet Challenges webinar.
