Skills and Abilities

Objective 2.3 – Configure and Manage Routing

  • Deploy the appropriate NSX Edge (ESG/DLR) device according to a deployment plan.
  • Configure centralized and distributed routing.
  • Configure default gateway parameters.
  • Configure static routes.
  • Select and configure appropriate dynamic routing protocol according to a deployment plan:
    • OSPF
    • BGP
    • IS-IS
  • Configure route redistribution to support a multi-protocol environment.

Objective Prerequisites

The following prerequisites are assumed for this Objective:

  • A working VMware vSphere 6.x environment.
  • A working VMware NSX 6.x environment.

Objective Breakdown

Deploy the appropriate NSX Edge (ESG/DLR) device according to a deployment plan

A VMware NSX Edge Services Gateway (ESG) is deployed for North/South traffic and the additional services, such as NAT and Load Balancing.  In most circumstances, a VMware NSX Distributed Logical Router (DLR) is deployed for East/West traffic.  Although it is possible to configure a uplink to allow North/South traffic on a DLR.

For DLR, see HOWTO: Deploy a VMware NSX Distributed Logical Router (DLR)

For ESG, see HOWTO: Deploy a VMware NSX Edge Services Gateway (ESG)

Configure centralized and distributed routing

I’m not sure what specific things I should cover here that isn’t covered in other parts of this objective.

Configure Default Gateway parameters

Note: These steps assume you are not even logged into vCenter Server.  Skip the first few steps if you are!

Using your favourite web browser, navigate to the vCenter Server login page (https://vcenter.fqdn).

Enter appropriate User name and Password and click Login.

Click Networking and Security.

Click NSX Edges.

Double-Click on the target NSX Edge.

Click the Manage Tab, select Routing and click Global Configuration.

At Default Gateway, click Edit.

Select the Interface from the dropdown, enter the Gateway IP address, (optional) update the MTU value and Admin Distance.

Click OK.

Click Publish Changes.

Configure Static Routes

Note: These steps assume you are not even logged into vCenter Server.  Skip the first few steps if you are!

Using your favourite web browser, navigate to the vCenter Server login page (https://vcenter.fqdn).

Enter appropriate User name and Password and click Login.

Click Networking and Security.

Click NSX Edges.

Double-Click on the target NSX Edge.

Click the Manage Tab, select Routing.

Click Static Routes.

Click Add(+).

Enter the Network (CIDR format) address, enter the Next Hop, select the Interface from the dropdown.

Click OK.

Click Publish Changes.

Repeat the steps on each DLR and ESG as required…

Select and configure appropriate dynamic routing protocol according to a deployment plan: OSPF

See HOWTO: Configure VMware NSX with Dynamic Routing – OSPF

Select and configure appropriate dynamic routing protocol according to a deployment plan: BGP

See HOWTO: Configure VMware NSX with Dynamic Routing – BGP

Select and configure appropriate dynamic routing protocol according to a deployment plan: IS-IS

This Routing Protocol has been removed in NSX 6.3 and therefore I have no way to document this.  Checkout the VMware Docs for more information.

Configure route redistribution to support a multi-protocol environment

By default, routers share routes with other routers running the same protocol. In a multi-protocol environment, you must configure route redistribution for cross-protocol route sharing.

Using your favourite web browser, navigate to the vCenter Server login page (https://vcenter.fqdn).

Enter appropriate User name and Password and click Login.

Click Networking and Security.

Click NSX Edges.

Double-Click on the target NSX Edge.

Select the Manage tab, select Routing and then select Route Redistribution.

At Route Redistribution Status, click Edit.

Check both the OSPF and BGP checkboxes.

Click OK.

Under IP Prefixes, click Add(+).

Enter a Name for the IP Prefix and then a IP/Network in CIDR format.

Click OK.

Note: Add Additional IP Prefixes as required.

At Route Redistribution Table, click Add(+).

Select the Prefix Name (Any), the Learner Protocol (OSPF/BGP), check the appropriate Allow Learning from checkboxes and select Permit from the Action dropdown.

Click OK.

Click Publish Changes.
