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
