Building Microsoft System Center Cloud – SCVMM 2012 R2 – Networking – Logical Networks and Network Sites

Logical Network

Logical Network is way how to define network that has same purpose. Logical Network can be for example Infrastructure network for Hyper-V hosts in all your datacenters (in multiple sites) and another Logical Network could be a network that is used by VMs of one tenant or multiple tenants (network virtualization).

Naming conventions

You can read about my naming convention in the first networking article.

  • LN-<Logical Network>

Network Site

Logical Network is composed from one or more sites.

Naming conventions

You can read about my naming convention in the first networking article.

  • LNS-<Logical Network>-<Network site>

Default Logical Networks

Logical Networks and VM Networks was pre-created by VMM using information from the hosts. On all hosts there is a virtual switch named Production and therefore I can find Production Logical Network in VMM.

  • Default Logical Network

Create new Logical Network and Network Sites

  • Fabric – Logical networks – Create Logical Network
  • Set name and choose if you want to use network virtualization. Without setting network virtualization you will not be able to set Hyper-V isolation in the VM Network.
    • Not using network virtualization (Hyper-V isolation)…
        • LN-Infrastructure
      • Set network sites. You need to specify one or multiple VLAN and IP address pairs or just IP addresses (VLAN 0).
      • No VLAN means zero. You can check it and open the properties of the Logical Network and check that there is explicitly defined a zero.
      • Also specify host groups where you can use this network site.
          • LN-Infrastructure-Big datacenter
          • LN-Infrastructure-Small datacenter
    • Using network virtualization (Hyper-V isolation)…
        • LN-Contoso
      • Set network sites.
          • LN-Contoso-Big datacenter
          • LN-Contoso-Small datacenter
