Associating a bridge domain with an external network

Now that we have a routed interface, we must associate it with the bridge domain.

How to do it…

1. Navigate to TenantA | Networking | Bridge Domains | TenantA-BD.

2. Click on L3 Configurations on the right-hand side.
3. If required, you can add additional subnets here as well. In the following screenshot, I have added the 10.2.20.0/24 subnet.
4. Select TenantA-Routed for L3 Out under Associated L3 Outs.

5. Select the same L3 Out for the L3 Out for Route Profile.

6. Click on SUBMIT. One issue here is that we will not be advertising any routes. If you have a successful peering to another BGP speaker, you will see that you will receive routes advertised to you, but the other speaker will not receive any prefixes from the tenant. Therefore, we must make a small change.

 

7. Navigate to TenantA | Networking | Bridge Domains | TenantA-BD | Subnets, and click on the 10.2.20.1/24 subnet.

8. Tick the Advertised Externally box.

9. Click on SUBMIT.
10. Return to the TenantA-BD bridge domain...
