NSX logical switches
Using VMware NSX virtual networks, we can create a logical network on top of any IP network. We have already discussed VXLAN fundamentals and the host installation process in the previous chapters. Now that we have a good understanding of the basics, it's time to move on with virtual network creation. Before we begin exploring, it is important to understand that each logical network is a separate broadcast domain.
Logical network prerequisites
Firstly, let's have a look at the prerequisites for logical network creation:
- Host preparation
- Segment ID (VNI) pool
- Global transport zone
Host preparation
We have already discussed in detail how the underlying ESXi host is prepared from NSX Manager in Chapter 3 , NSX Manager Installation and Configuration. Here, it is time to recollect that knowledge.
The hypervisor kernel modules enable ESXi hosts to support VXLAN, the logical switch, the distributed router, and the distributed firewall.
Segment ID (VNI) pool
As we know, the...
