NSX Edge is a feature rich gateway Virtual Machines which offers L3-L7 services. Edge Gateway is the glue that connects all logical networks provide DHCP, NAT, Routing, VPN, Firewalling, Load Balancing and HA functionality. Ideally these devices will be configured at the perimeter level of vSphere Datacenter.
In this chapter, we will cover the following topics:
- Introducing Edge services
- Introducing Edge service form factors
- Introducing OSPF, BGP, and ISIS protocols
- Routing between DLR and NSX Edge router
- NSX Edge service use cases
NSX Edge gateway is a virtual machine that provides services such as Network Address Translation, Dynamic Host Configuration Protocol, DNS relay, Virtual Private Network, load balancing, and routing functionality. Firstly, there is no rule of thumb that says we should leverage all these features using one single Edge. For true multi-tenancy, we can deploy multiple Edges for different features' use cases. Let's have a look at Edge gateway form factor before we start with routing and other topics.
