New Year Wishes!!! Now that we covered the concepts, deployment, basic operations and maintenance of vSphere with Tanzu and TKG clusters in the previous articles, it’s time to walkthrough the NSX-T architecture used in the platform. At the time of writing this article, we have two networking options available for vSphere with Tanzu (since vSphere…… Continue reading NSX-T Architecture in vSphere with Tanzu – Part 1 – Per TKG Tier1 vs Per Namespace Tier1

NSX-T Single N-VDS Multi-TEP Baremetal Edges Deployment and Configuration
With the release of version 2.4, NSX-T now supports a Single N-VDS and Multi-TEP Baremetal Edge Configuration. With a Multi-TEP design, we could achieve redundancy when a TEP uplink fails instead of failing over to the Stand-by Edge node. This is the recommended configuration when we have two or more DPDK interfaces for the Baremetal…… Continue reading NSX-T Single N-VDS Multi-TEP Baremetal Edges Deployment and Configuration
NSX-T Tier0 AS-Multipath-Relax Explained
NSX-T introduced support for BGP AS-Multipath-Relax from version 2.4 which helps to achieve ECMP accross eBGP Leaf Switch Peers that differ in ASN path attribute values, but have the same AS-path length. As I mentioned in my previous article on ECMP routing, lets revisit the requirements to be met to achieve ECMP between the T0…… Continue reading NSX-T Tier0 AS-Multipath-Relax Explained
NSX-T Tier0 ECMP Architecture and Routing Explained
NSX-T Tier0 Gateway supports ECMP in BGP routing with the Leaf Switches which helps utilizing all the Edge Uplinks for Egress and Ingress traffic. ECMP mode is available only when the Tier0 Gateway is deployed in Active-Active mode. ECMP is applied at three levels: T0 DR-SR ECMP : Between the T0 DR component and T0…… Continue reading NSX-T Tier0 ECMP Architecture and Routing Explained
NSX-T Tier0 Inter-SR Routing Explained
Inter-SR Routing is an iBGP peering feature between the SR Components of the Tier 0 Gateway deployed in Active-Active mode. This feature helps to tolerate an asymmetric failure of the SR component on the Edge node by routing the internal traffic reaching to it over the iBGP inter-SR link to the SR component on the…… Continue reading NSX-T Tier0 Inter-SR Routing Explained
Deploying and Configuring NSX-T Edges on N-VDS Networking
NSX-T Edges have flexible deployment options based on the host networking that is used. We can deploy NSX-T Edges on Distributed vSwitches (which is managed by vCenter Server) or on host N-VDS (which is managed by NSX-T). NSX-T Edges deployment and configuration on DvSwitches has been covered in my previous post, you can find it…… Continue reading Deploying and Configuring NSX-T Edges on N-VDS Networking
NSX-T T0 Active-Active Gateway and BGP Peering with Dell Networking ToR Switches
NSX-T supports BGP as the only dynamic routing protocol to peer the Edges (T0 Gateways) with the customer network. BGP is supported only on the Tier 0 gateways unlike NSX-V which supports dynamic routing on both the DLR and ESGs. Peering of T1 and T0 Gateways are fully managed by NSX-T and is transparent to…… Continue reading NSX-T T0 Active-Active Gateway and BGP Peering with Dell Networking ToR Switches
NSX-T Edges – Baremetal vs VM Comparison
NSX-T Edge Nodes come in two form factors – VM and Baremetal both leveraging Intel DPDK (Data Plane Development Kit) acceleration for the transport and Uplink networks. Deciding which form factor to use depends upon on our use case requirements and it is good to understand the workload traffic behavior and virtualized services requirement before…… Continue reading NSX-T Edges – Baremetal vs VM Comparison
NSX-T L2 Bridging between Overlay & VLAN segments – Part 2
In Part 1 we discussed how to implement NSX-T L2 bridging between Overlay & VLAN segments using ESXi Bridge Clusters. If you didn’t get a chance to go through my previous article, you can find it here: https://vxplanet.com/2019/06/06/implementing-nsx-t-l2-bridging-between-overlay-vlan-segments-part-1/ In this post we will discuss how to implement L2 bridging using NSX-T Edge Clusters. To iterate,…… Continue reading NSX-T L2 Bridging between Overlay & VLAN segments – Part 2
NSX-T L2 Bridging between Overlay & VLAN segments – Part 1
NSX-T supports L2 bridging between Overlay logical segments and physical VLAN segments. Unlike NSX-V, NSX-T doesn’t have support for hardware VTEPs (because the ToRs are yet to support the Geneve encapsulation, they are still on VxLAN). With NSX-T, for these requirements, the option is to do an L2 Bridging on the Edges leveraging DPDK acceleration…… Continue reading NSX-T L2 Bridging between Overlay & VLAN segments – Part 1
