What’s New in VMware NSX Data Center for vSphere 6.4.2
With this latest release, VMware NSX Data Center for vSphere 6.4.2 continues to improve overall efficiency of the network, enhance security with Context-Aware Micro-Segmentation, and deliver operational enhancements to the NSX platform. Here are just a few highlights of what’s new.
Multicast Routing Support
With VMware NSX Data Center for vSphere 6.4.2, NSX Logical Routers now have the capability of routing IPv4 multicast traffic.
The location of the Virtual Machine multicast receivers (identified by their hypervisor, Logical Switch and Virtual NIC) is discovered thanks to IGMP snooping within the NSX domain. The Edge Service Gateway (ESG) runs PIM sparse mode with physical routers and coordinates with the Distributed Logical Router (DLR) in order to provide both ways multicast connectivity from Virtual Machines to the outside world.
For added multicast replication performance in the VXLAN Overlay, NSX leverages Layer 2 multicast in an underlying physical infrastructure running IGMP snooping.
Context-Aware Micro-Segmentation
New Layer 7 Application Context
VMware has been taking security to the next level with Context-Aware Micro-Segmentation, better securing application using the full context of the application. This latest release includes the following new Layer 7 Application Context:

SANOG 32 – Another Success Story for MANRS
The SANOG 32 meeting was held on 2-10 August 2018 in Dhaka, Bangladesh, which marked fifteen amazing years of collaboration between network operators in the South Asia region. The Internet Society is proud to support the SANOG fellowship programme that provides opportunities for network engineers from countries in the region to attend, as well as organising the Network Security workshop during the event.
SANOG 32 also saw another MANRS milestone reached when the ISP Association of Bangladesh (ISPAB) signed a Memorandum of Understanding (MoU) with the Internet Society. ISPAB is a membership-based, not-for-profit organization that provides a forum for Bangladeshi ISPs to discuss technology, policy, regulatory and commercial issues and find collective solutions.
In accordance with the MoU, both ISPAB and ISOC will work together to promote and support MANRS, to encourage network operators in Bangladesh to join the initiative. There are currently only two MANRS participants in the country, so being able to increase engagement with the networking community is a welcome development.
Dr Philip Smith (NSRC and Chair of SANOG Programme Committee) also provided a MANRS update during the conference session.
The Network Security workshop attracted 40 participants and was lead by MANRS founding member Matsuzaki Yoshinobu (IIJ) and Continue reading
Dell EMC Touts ‘Kinetic’ Composable Infrastructure in VMworld Ramp Up

Bootstrapping an etcd Cluster with TLS using Kubeadm
The etcd distributed key-value store is an integral part of Kubernetes. I first wrote about etcd back in 2014 in this post, but haven’t really discussed it in any great detail since then. However, as part of my recent efforts to dive much deeper into Kubernetes, I needed to revisit etcd. In this post, I wanted to share how to boostrap a new etcd cluster with TLS certificates using kubeadm.
Before I go on, I feel compelled to state that this is certainly not the only way to bootstrap an etcd cluster with TLS certificates. I feel I must also state that nothing in what I’m about to share is new, novel, revolutionary, or unusual. In fact, a fair amount of it is based on these instructions, although this post will focus on using systemd unit files instead of static pods under Kubernetes. I’m simply documenting it here in the hopes of getting the information more broadly disseminated, and to help document my own journey of learning.
Preparing the Systems
Before you bootstrap the etcd cluster, you’ll first need to prepare the nodes for the process. Although I’ll list the steps manually below, in practice you’ll want to Continue reading

Rethinking Security in Cloud Networking
Every CXO worries about security because the perimeter is changing; in fact, there are no walls for protection. The lines between cloud, workloads, applications, enterprise networks and hosts are blurring and the challenges are getting exponentially greater. The true security architect must rapidly address the reality of a more holistic network-wide security strategy. It must be one that goes beyond the cyber threat of the day to address the risk, scale and mitigation of persistent security issues. The state of cyber security needs urgent resolution because:
