Adding Tiers

Adding Tiers Tiers are distinct locations within a VPC that act as isolated networks, which do not have access to other tiers by default. Tiers are set up on different VLANs that can communicate with each other by using a virtual router. Tiers provide inexpensive, low latency network connectivity to other tiers within the VPC. Log in to the &PRODUCT; UI as an administrator or end user. In the left navigation, choose Network. In the Select view, select VPC. All the VPC that you have created for the account is listed in the page. The end users can see their own VPCs, while root and domain admin can see any VPC they are authorized to see. Click the Configure button of the VPC for which you want to set up tiers. Click Create network. The Add new tier dialog is displayed, as follows: add-tier.png: adding a tier to a vpc. If you have already created tiers, the VPC diagram is displayed. Click Create Tier to add a new tier. Specify the following: All the fields are mandatory. Name: A unique name for the tier you create. Network Offering: The following default network offerings are listed: Internal LB, DefaultIsolatedNetworkOfferingForVpcNetworksNoLB, DefaultIsolatedNetworkOfferingForVpcNetworks In a VPC, only one tier can be created by using LB-enabled network offering. Gateway: The gateway for the tier you create. Ensure that the gateway is within the Super CIDR range that you specified while creating the VPC, and is not overlapped with the CIDR of any existing tier within the VPC. VLAN: The VLAN ID for the tier that the root admin creates. This option is only visible if the network offering you selected is VLAN-enabled. For more information, see the Assigning VLANs to Isolated Networks section in the &PRODUCT; Administration Guide. For more information, see . Netmask: The netmask for the tier you create. For example, if the VPC CIDR is 10.0.0.0/16 and the network tier CIDR is 10.0.1.0/24, the gateway of the tier is 10.0.1.1, and the netmask of the tier is 255.255.255.0. Click OK. Continue with configuring access control list for the tier.
