VMware NSX Configuration Part 2

I will be demonstrating following configuration tasks in this post
  • Configure Default Gateway in Logical Router as IP of Edge Services Gateway
  • Configure OSPF on Logical Router with Area ID 101
  • Configure Uplink Interface on Edge Services Gateway attached to VLAN based Port Group
  • Configure OSPF on Edge Services Gateway with Area ID 101

Configure Default Gateway in Logical Router

Navigate to Logical Router under NSX Edges and Click on Routing Tab. You may notice Default Gateway is not configured. Click on Edit and specify the details
You will need to publish the change to get it reflected
To Test the connectivity  SSH into the Edge Services Gateway and try pinging IP for Logical Router. It should work fine

Configure OSPF on Logical Router

This will help configure dynamic routing between Logical Router and Edge Services Gateway
Navigate to Logical Router under NSX Edges and Click on Routing Tab Press  Global Configuration
You may notice OSPF is Disabled under Dynamic Routing Configuration
Click on Edit and set the \”Router ID\”
Don’t forget to Publish the Changes
Navigate to the OSPF on the left
Specify the Uplink Interface Address as \”Forwarding Address\” and Chose any free IP from the same Range as \”Protocol Address\’
Don’t forget to publish
Now we will create an Area Definition for the communication between Logical Router and Edge Services Gateway
Don’t forget to publish the Changes. By now you would have already noticed that I prefer to public with each change I make
Next we will do Area to Interface Mapping
Publish the Changes

Configure Uplink Interface on Edge Services Gateway

Navigate to Edge Services Gateway under NSX Edges and Click on Settings Tab Press  Interface
Select vnic1 and Click Edit icon
Select the Transport VLAN Port Group  which has access to the External World
Make sure IP is reachable from external servers

Configure OSPF in Edge Services Gateway

This will help configure dynamic routing between Logical Router and Edge Services Gateway
Navigate to Edge Services Gateway under NSX Edges and Click on Routing Tab Press  Global Configuration
You may notice OSPF is Disabled under Dynamic Routing Configuration
Click on Edit and set the \”Router ID\”
 Navigate to the OSPF on the left
Please ensure to check Enable OSPF
Publish the Changes
Now we will create an Area Definition for the communication between Edge Services Gateway and Logical Router. Please ensure Area ID is the same we created in Logical Router
Publish the Changes
Next we will do Area to Interface Mapping
Publish the Changes

Tests

In order to Test I created a New Logical Switch Test and added Internal Interface on the Logical Router with IP Range of 172.17.1/24
I logged in the console for Edge Services Gateway to see if it propagated route automatically for 172.17.1.x
With this base configuration for NSX has been completed. Now if you need more Logical Switches you can create as per you design and map it to the Interface in Logical Router
There are additional Services which we can configure in Edge Services Gateway as per your requirement. I will try go demonstrate couple of them in future posts
Please feel free to provide comments if the posts have been helpful
