How to do it...

1. We start by going into the tenant we created in the previous recipe and going to Networking | Bridge Domains.

1. Click on Actions, and then on Create Bridge Domain.

1. This launches a new window. Here, we name our bridge domain and assign a VRF to it if we have already created one, or create a new VRF.

If we choose Create VRF, it brings up another window:

Because we have not created any timer policies for BGP or OSPF or a monitoring policy, we can leave these fields empty and use the default values.

1. Once we click on SUBMIT, the new VRF is selected:

1. We can set the forwarding to Optimize. Leave the End Point Retention Policy and IGMP Snoop Policy at the defaults, and click on NEXT to take us to the L3 Configurations window.

This is where we enable Unicast Routing and ARP flooding (if we want to), specify a MAC address and create a subnet.

1. To create a subnet, click on the plus sign, which brings up another window:

1. Here, we specify the subnet and subnet mask for the network and set the scope to be private, public (Advertised Externally), or shared.

1. Click on OK, which will take us back to the L3 Configurations window.
2. Click on NEXT to take us to the final window, where we can select a monitoring policy.

1. Click on FINISH.
