Example: Setting up Multi-Link and dynamic DNS updates

When you set up dynamic DNS updates, the Server Pool NetLink addresses that correspond to the available Internet connections are updated automatically on the DNS server.

The administrators at Company A have already configured a Server Pool (see the previous example). Now they want to make sure that web services remain available even when an Internet connection fails. They also want the Server Pool’s NetLink addresses to be automatically updated on the DNS server based on the availability of the Internet connections.

The administrators have already configured Multi-Link routing with the necessary NetLink elements to represent each of their Internet connections. A DNS server has also already been set up in the network. The administrators decide to add the NetLinks to the Server Pool and set up Dynamic DNS (DDNS) updates.
