6 Review the network settings and click Finish.
What to do next
You can now create an organization vDC network that connects to the external network.
Network Pools
A network pool is a group of undifferentiated networks that is available for use within an organization vDC
to create vApp networks and certain types of organization vDC networks.
A network pool is backed by vSphere network resources such as VLAN IDs, port groups, or Cloud isolated
networks. vCloud Director uses network pools to create NAT-routed and internal organization vDC networks
and all vApp networks. Network traffic on each network in a pool is isolated at layer 2 from all other networks.
Each organization vDC in vCloud Director can have one network pool. Multiple organization vDCs can share
the same network pool. The network pool for an organization vDC provides the networks created to satisfy
the network quota for an organization vDC.
Add a Network Pool That Is Backed by VLAN IDs
You can add a VLAN-backed network pool to register vSphere VLAN IDs for vCloud Director to use. A VLAN-
backed network pool provides the best security, scalability, and performance for organization vDC networks.
Prerequisites
Verify that a range of VLAN IDs and a vSphere distributed switch are available in vSphere. The VLAN IDs
must be valid IDs that are configured in the physical switch to which the ESX/ESXi servers are connected.
CAUTION The VLANs must be isolated at the layer 2 level. Failure to properly isolate the VLANs can cause a
disruption on the network.
Procedure
1 Click the Manage & Monitor tab and click Network Pools in the left pane.
2 Click Add Network Pool.
3 Select VLAN-backed and click Next.
4 Type a range of VLAN IDs and click Add.
You can create one network for each VLAN ID.
5 Select a vCenter Server and vSphere distributed switch and click Next.
6 Type a name and optional description for the network and click Next.
7 Review the network pool settings and click Finish.
What to do next
You can now create an organization vDC network that is backed by the network pool or associate the network
pool with an organization vDC and create vApp networks.
Add a Network Pool That Is Backed by Cloud Isolated Networks
You can create a network pool that is backed by cloud isolated networks. A cloud isolated network spans hosts,
provides traffic isolation from other networks, and is the best source for vApp networks.
An isolation-backed network pool does not require preexisting port groups in vSphere.
Prerequisites
Verify that a vSphere distributed switch is available.
