Dell VRF-lite & VMware NSX: Multitenancy Across Physical & Logical Networks

Saturday, December 20th, 2014

Please checkout the white paper Dell Networking: Multitenancy Across Physical and Logical Environments with VRF-lite and VMware NSX. In the white paper I discuss use cases and how NVO and VRF-lite can be used together to deploy a consistent multitenant framework across logical and physical networks. In this short blog, I expand on the concept I presented in a prior blog, Multitenancy on Dell Networking Switches via VRF-lite, of how NVO and VRF-lite together can be used to deploy a consistent multitenant framework across logical and physical networks.

Multitenancy on Dell Networking Switches via VRF-lite

Wednesday, October 29th, 2014

Check out the Dell Networking: Multitenancy with VRF-lite white paper. I describe in detail how multitenency can be achieved on supported Dell Networking switches via Virtual Routing and Forwarding (VRF). VRF-lite supports multitenancy by allowing multiple different routing tables within one physical L3 switch/router. This allows for a multitenant network without having to buy additional hardware. In the diagram directly below, each color represents a different customer tenant utilizing the same IP address space (overlapping IP addresses). Such a setup can also be useful for development and testing where traffic isolation is needed; the overlapping IP addresses can be used for ensuring consistency between each development/test environment.

Cisco Nexus 5548UP – Configuring the Management Interface

Wednesday, July 3rd, 2013

This is a relatively simple blog on configuring the Cisco Nexus 5548UP management interface. When Cisco moved away from IOS to NX-OS for the operating system on their new Nexus datacenter switches, some of the commands and syntax for even the simplest tasks have changed. For easy reference for a common task such as setting the management interface I decided to write this quick blog. The network diagram is below. I am using a Dell S4810 [FTOS 9.1] for my management switch to which both the Dell PowerEdge R710 server and Cisco Nexus 5548UP [NX-OS 5.2(1)N1(1b)] connect. I also use a 1000Base-T SFP transceiver to convert the Dell S4810 fiber port to copper, so I can connect it to the management port of the Cisco Nexus. (more…)
