NSX-T Logical Routing



NSX-T logical routing is a powerful feature of the NSX-T networking and security platform that allows for flexible and scalable routing of traffic between virtual and physical networks. With NSX-T logical routing, you can create logical routers that can route traffic between virtual networks, physical networks, and even across different cloud environments. In this article, we will explore the benefits of NSX-T logical routing, how it works, and some best practices for its implementation.


Benefits of NSX-T Logical Routing

NSX-T logical routing offers several key benefits, including:

Scalability: NSX-T logical routing provides a scalable solution for routing traffic between virtual and physical networks, allowing you to easily scale your network infrastructure as your organization grows.

Flexibility: NSX-T logical routing provides a flexible solution for routing traffic between different networks and cloud environments, allowing you to easily connect your virtual and physical infrastructure to create a cohesive network architecture.

Simplified Management: NSX-T logical routing simplifies network management by providing a single pane of glass for managing routing policies across multiple virtual and physical networks.


How NSX-T Logical Routing Works

NSX-T logical routing works by creating logical routers that can route traffic between virtual and physical networks. These logical routers are created using NSX-T Manager, which allows you to define routing policies and configure interfaces for each logical router.

Once a logical router is created, you can then configure routing policies to control how traffic is routed between virtual and physical networks. For example, you can configure static routes or use dynamic routing protocols such as OSPF or BGP to dynamically route traffic between networks.


Best Practices for Implementing NSX-T Logical Routing

When implementing NSX-T logical routing, it is important to follow best practices to ensure optimal performance and security. Some best practices to consider include:

Segmentation: Use network segmentation to separate traffic between different logical routers to improve security and reduce the risk of unauthorized access to sensitive data.

Redundancy: Implement redundant logical routers to ensure high availability and reduce the risk of network downtime.

Performance Optimization: Optimize routing performance by configuring routing policies to minimize the number of hops required to route traffic between networks.

Security: Use NSX-T security features such as Distributed Firewall and Micro-segmentation to enhance security and protect against threats.


NSX-T logical routing is a critical component of the NSX-T platform, providing organizations with the ability to build complex, multi-tenant networks that can support a variety of applications and services. NSX-T logical routing can also help organizations achieve compliance with regulatory requirements such as PCI-DSS and HIPAA by providing a secure and segmented network architecture.

One of the key benefits of NSX-T logical routing is its ability to route traffic across different cloud environments. With NSX-T logical routing, organizations can easily connect their virtual and physical infrastructure to cloud environments such as AWS, Azure, and Google Cloud Platform. This allows organizations to build hybrid cloud architectures that can provide greater flexibility and cost savings than traditional on-premises solutions.

NSX-T logical routing also provides organizations with the ability to create virtual networks that are completely isolated from one another. This can help organizations meet regulatory requirements for data privacy and security, and can also help prevent unauthorized access to sensitive data. Additionally, NSX-T logical routing allows organizations to create multiple virtual routing domains within a single physical network, providing a high degree of flexibility and control over network traffic.


When implementing NSX-T logical routing, it is important to consider the impact on network performance. While NSX-T logical routing can provide a scalable and flexible solution for routing traffic, it can also introduce additional latency and overhead. To optimize network performance, it is important to carefully configure routing policies and implement strategies such as route aggregation and summarization.


Summary

NSX-T logical routing is a powerful and flexible solution for routing traffic between virtual and physical networks. By following best practices for implementation and optimization, organizations can build secure and scalable network architectures that can support a variety of applications and services.

Changing the FQDN of the vCenter appliance (VCSA)

This article states how to change the system name or the FQDN of the vCenter appliance 6.x You may not find any way to change the FQDN from the vCenter GUI either from VAMI page of from webclient as the option to change the hostname always be greyed out. Now the option left is from the command line of VCSA appliance. Below steps will make it possible to change the FQDN of the VCSA from the command line. Access the VCSA from console or from Putty session. Login with root permission Use above command in the command prompt of VCSA : /opt/vmware/share/vami/vami_config_net Opt for option 3 (Hostname) Change the hostname to new name Reboot the VCSA appliance.   After reboot you will be successfully manage to change the FQDN of the VCSA . Note: Above step is unsupported by VMware and may impact your SSL certificate and face problem while logging to vSphere Web Client. If you are using self-signed certificate, you can regenerate the certificate with the

Issue : Configure Management Network option is Grayed out into ESXi

Last week I got into an issue of one of my client into Vsphere environment where one of its ESXi went done out of the network. Issue was IP address was showing 0.0.0.0 on main Esxi screen and when I tried to change the network configuration, its " Configure Management network option was greyed out.  I tried to gid into it and try to analyis its vmKernal and vmwarning logs. What I found is its VMkernal switch got removed due to unexpected reason. So to resolve the issue I tried to reconfigure its vswitch0 (vmk0) by going into Tech Mode of that Exi. Below are the steps which I followed to resolve the issue. 1) Login to ESXi 2) Press F2, Check if you " Configure Management network " is greyed out or not" if yes,    follow below 3) Press ALT+F1 to move the ESXi screen to tech mode   ( This is command line like dos) 4) login with root account 5) Run the following command into it esxcli network ip interface add --interface-name= vmk0

Collecting Logs from NSX-T Edge nodes using CLI

  This article explains how to extract the logs from NSX-T Edge nodes from CLI. Let's view the steps involved: 1) Login to NSX-T  Edge node using CLI from admin credentials. 2) Use of  " get support-bundle " for Log extraction. get support-bundle command will extract the complete logs from NSX-T manager/Edge nodes. nsx-manager-1> get support-bundle file support-bundle.tgz 3) Last step is to us e of " copy file support-bundle.tgz url " command. copy file will forward your collected logs from the NSX-T manager to the destination(URL) host from where you can download the logs. copy file support.bundle.tgz url scp://root@192.168.11.15/tmp Here, the URL specified is the ESXi host ( 192.168.11.15) under /tmp partition where logs will be copied and from there one can extract it for further log review. Happy Learning.  :)
