Objective 4.1 – Configure Environment for Network Virtualization

Knowledge

• Configure the physical infrastructure (MTU, Dynamic Routing for edge, etc.)
  • MTU needs to be 1600 for transport zone
    Can use 1550 if you aren’t going to have VLAN tagging in the VM Guest OS
    Has been suggested that 1600 is the minimum recommended in 6.0, and 1550 is the minimum recommended in 6.1
  • Configure OSPF adjacency for routing on Edge (or BGP, ISIS equivalent)
• Prepare a new vSphere infrastructure
  • Configure Quality of Service (QoS)
    • L2/L3 fabric must be configured to trust the hypervisor for QoS marking – hypervisor is the trusted boundary.
  • Configure Link Aggregation Control Protocol (LACP)
    • Can use LACP or Etherchannel for the Transport network, but only a single VTEP is supported with bonded channels.
• Configure an existing vSphere infrastructure
  • Ensure DNS entries are configured correctly for all components
  • Requires vSphere 5.5 and vCenter 5.5
  • Upgrade VMware Tools – minimum 8.6, vHW 7+
  • Must use Enterprise+ license

• Explain how IP address assignments work in VMware NSX
  • Can use IP Pools or DHCP to assign addresses for NSX components. DHCP allows configuration of VTEP on different VLANs, whereas IP Pools require the same VLAN or manual configuration to change after install.
• Identify minimum permissions required to deploy NSX in a vSphere environment
  • Administrative access to vCenter – required to synchronise the NSX Manager with vCenter

Tools

• vSphere Networking Guide
• NSX Administration Guide
• vSphere Web Client
