The loopback interface is supported in routed mode only. In the loopback interface configuration, you can specify a primary IPv4 address, and you can add secondary networks. A loopback interface can increase the stability of dynamic routing through a multi-WAN connection because it ensures the consistency of the next hop and avoids the potential for BGP routing oscillation. You can use the loopback interface for dynamic routing to multiple ISPs when your Firebox is configured with multi-WAN. These IP address usually provided by ISPs (Internet Service Provider).ĭid you find this guide helpful?
