Guided Exercise: Managing Provider and External Networks

In this lab, you will create a provider network using the Dashboard.

Outcomes

You should be able to create a provider network using the Dashboard.

As the student user on the workstation machine, use the lab command to prepare your system for this exercise.

This command ensures that all resources required for this exercise are present.

[student@workstation ~]$ lab public-networks start

Procedure 7.1. Instructions

  1. Log in to the Dashboard as the admin user, using default as the domain name and redhat as the password. Create a VLAN provider network named provider2-104 with a matching subnet named subnet2-104. Use the details from the following table.

    OptionValue
    External Network 
    Shared 
    Provider Network Type vlan
    Physical Network vlanprovider2
    Segmentation ID 104
    Enable DHCP 
    Network Address 10.0.104.0/24
    Allocation Pools start=10.0.104.100,end=10.0.104.149

    1. On workstation, open Firefox and navigate to http://dashboard.overcloud.example.com. Log in to the Dashboard using default as the domain name, admin as the user name, and redhat as the password.

    2. Ensure that the selected project is admin. Click Admin at the upper-left corner of the Dashboard.

      Note

      If the Admin tab is not visible, ensure that the admin project is selected.

    3. Navigate to Network → Networks and click Create Network.

    4. Enter provider2-104 as the name, select admin as the project, and select VLAN as the provider network type.

      Enter vlanprovider2 as the physical network. Set the segmentation ID to 104.

      Ensure that Enable Admin State, Shared, External Network, and Create Subnet are all selected, and then click Next.

    5. Enter subnet2-104 as the subnet name. Set the network address to 10.0.104.0/24. Leave the Gateway IP field blank. Click Next.

    6. Ensure that the Enable DHCP option is selected. In the Allocation Pools field, enter 10.0.104.100,10.0.104.149. Leave the other boxes blank. Click Create.

  2. In the Dashboard, confirm that the new VLAN provider network is created. Ensure that the network is shared, external, and active. Confirm that the network has a DHCP port.

    1. On the Networks tab, locate provider2-104. Ensure that the network is shared, external, and active.

    2. Click the provider2-104 network and then click Ports. Verify that the DHCP port has a fixed IP address of 10.0.104.100.

  3. In the Dashboard, review the network topology for the domain.

    1. Navigate to Project → Network → Network Topology and locate the provider2-104 network.

Finish

On the workstation machine, use the lab command to complete this exercise. This is important to ensure that resources from previous exercises do not impact upcoming exercises.
