Enabling BGP in ACI fabric

Hello Friends Today, I will be showing how we can enable BGP in the ACI fabric i.e. between the Spine and the Leaf switches. Between the Spine and the leaf switches, only two protocols are run. One is BGP and the other is ISIS. ISIS is enabled by default. You need to manually configure / enable BGP. The BGP session that we bring up between the Spine and the leaf is MP-BGP session and the Spine nodes always act as a route-reflector. The MP-BGP session is only required for External L3 connections to the ACI fabric. For the internal connections, MP-BGP is not required. In order to demonstrate h... [More]

Software Defined Networking with Cisco ACI

Hello Friends, Today we are going to discuss on a very hot topic which is booming in the networking industry and that is SDN. But we are not going to understand SDN here but we will be seeing what is Cisco's solution to SDN. Before we start our discussion, lets understand what SDN means and how it works? SDN (Software Defined Networking) as the name suggests means managing the network the way you want by writing a small piece of code to achieve the task. As per ONF (Open Network Foundation), "Software-Defined Networking (SDN) is an emerging architecture that is dynamic, manageable, cost...
