This article assumes that you have read and understand the previous article concerning the Cisco Nexus 1000V Architecture. These posts are excerpts from the material covered in the upcoming IPexpert CCIE Data Center Written bootcamp.

Preparing the ESX Servers

In order to run the Nexus 1000V Virtual Ethernet Module (VEM) on a VMware ESX server, you must install the VMware Enterprise Plus license.

The Virtual Supervisor Module (VSM) can run in a VMware Virtual Machine (VM). The VSM VM must possess 4 GB of memory, 2 Network Interface Cards (NICs) – one for management traffic and one for data traffic, and a 64-bit CPU.

The upstream switches must be configured to trunk the VLANs that you intend to use for control, management, packet, vMotion, and VM traffic.

Finally, ensure that a data-center object is created to contain your ESX servers in vCenter.

In a previous post about the Next Hop Resolution Protocol (NHRP), we examined the theory and functionality of NHRP. In this post, we will examine the configuration commands that make NHRP possible. This will conclude the information that is required to be known about this important protocol for the written exam. NOTE: This does not conclude information that should be known about the main use of NHRP – the Dynamic Multi-point VPN (DMVPN). That is a topic for other blog posts.
