NSX-T Single NVDS Multi-TEP Edge VM Deployment & Configuration on Host NVDS Networking

NSX-T introduced a Single NVDS Multi-TEP design for the Edge nodes in version 2.4, with recommendation to use from version 2.5 onwards. With this new design, we could now achieve better load balancing for the overlay traffic as well as have a consistent deployment model for both VM and BM edge form factors. A consistent…… Continue reading NSX-T Single NVDS Multi-TEP Edge VM Deployment & Configuration on Host NVDS Networking

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

BGP Load sharing and Unequal Cost Load sharing

Hi everyone, in this blog post we will walk through how to enable eBGP Equal Cost Multipathing (ECMP) and Unequal Cost multipathing. This comes into play when you are multihomed to different ISPs (AS’s). By default, BGP is not designed to perform load balancing, but it can be configured to do so. BGP will always…… Continue reading BGP Load sharing and Unequal Cost Load sharing
