What is an Edge Service Gateway (ESG)?
An Edge Services Gateway is a virtual appliance that is responsible for both North/South traffic and various Edge services, including Load Balancing, NAT and DHCP.
In this example, we will create a new ESG with two interfaces, one to connect to the transit network (Internal) and one to connect to a vDS Portgroup (Uplink).

What is a Distributed Logical Router (DLR) ?
A Distributed Logical Router (or Logical Distributed Router) is typically used to route East/West traffic between Logical Switches.
In this example, we will create a new DLR with two Internal interfaces to connect the App_Tier and Data_Tier Logical Switches. FInally we’ll add an Uplink interface to connect the DLR to a “transit” logical switch.

Skills and Abilities
Objective 2.2 - Configure and Manage Layer 2 Bridging
- Add Layer 2 Bridging
- Connect Layer 2 Bridging to the appropriate distributed virtual port group
Objective Prerequisites
The following prerequisites are assumed for this Objective:
- A working VMware vSphere 6.x environment.
- A working VMware NSX 6.x environment.
The following prerequisites are for Layer 2 Bridging.
- An NSX logical router must be deployed in your environment.
- You cannot use a universal logical router to configure bridging, and you cannot add a bridge to a universal logical switch.
Objective Breakdown
Add Layer 2 Bridging
Note: These steps assume you are not even logged into vCenter Server. Skip the first few steps if you are!

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.

Skills and Abilities
Objective 5.3 - Configure and Manage Role Based Access Control
- Implement identity service support for Active Directory, NIS, and LDAP with Single Sign-On (SSO).
- Manage User rights:
- Assign roles to user accounts
- Change a user role
- Delete/disable/enable a user account
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
Implement identity service support for Active Directory, NIS, and LDAP with Single Sign-On (SSO)
Configuring SSO requires that NTP is configured correctly within the VMware NSX Manager. This is covered in HOWTO: Deploy and Configure the VMware NSX Manager Virtual Appliance - Part 2

Skills and Abilities
Objective 8.1 - Administer and Execute calls using the VMware NSX vSphere API
- Construct and execute an API call using correct syntax and formatting
- Programmatically configure system parameters including:
- NSX controller syslog
- Modify DLR declared dead time
- Analyze, modify, and successfully retrieve configuration data using an existing API call.
Objective Prerequisites
The following prerequisites are assumed for this Objective:
- A working VMware vSphere 6.x environment.
- A working VMware NSX 6.x implementation.
Objective Breakdown
Construct and execute an API call using correct syntax and formatting
For API calls I tend to use Postman. I’m not sure how you can get the incorrect syntax when using the API guide from VMware. Within Postman, you choose the Request Type (i.e. GET, POST, DELETE, etc) and then enter the full URL of the API call.
