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

NSX-T Multi N-VDS Single-TEP Baremetal Edges Deployment and Configuration

NSX-T Edges come in two form factors – VM & Baremetal both leveraging DPDK libraries, and each having it’s own use case requirements. Prior to version 2.4, NSX-T supported only a single-TEP baremetal Edge design. This design required the need for a minimum of 3 Interfaces with a recommendation of 4. Dedicated interfaces were required for…… Continue reading NSX-T Multi N-VDS Single-TEP Baremetal Edges Deployment and Configuration

NSX-T N-VDS Topologies and Migrating Host Networking between vSphere DVS & N-VDS

NSX-T deploys its own host networking switch on the ESXi /KVM Transport hosts called N-VDS – the Next Generation Distributed Switch. The difference from the vSphere DvSwitch is that N-VDS spans across multiple hypervisors (ESXi, KVM etc) that are a part of the Transport zone (and configured as a Transport node) and that each transport…… Continue reading NSX-T N-VDS Topologies and Migrating Host Networking between vSphere DVS & N-VDS

Deploying the NSX-T 2.4 Edge VM Cluster leveraging vSphere DVS PortGroups

NSX-T Edge Clusters are responsible for the North-South traffic flow in the NSX-T SDDC. They can be deployed in VM Form Factor as well as Bare metal leveraging the DPDK libraries for high network performance. Edge Clusters host the DR and SR components of the logical routers that you deploy and is mandatory if you…… Continue reading Deploying the NSX-T 2.4 Edge VM Cluster leveraging vSphere DVS PortGroups
