Tracking and metric are both used for redundancy. Metric is more used for. Static routing to prefer a router over the other. However tracking is used to check if a route is down based on parameters you specify. Once the parameter is matched you will use the other route. <br>For example you track google ip to check if the internet went down so you can use the other route. <br>That's why in your image you see that the tracking is an option however the metric is not.&nbsp;

On my Cisco ASA I want to have a preferred and a backup route to (example) 1.1.1.1.
Would I make use of the Tracked mechanism to monitor the gateway IP and give it
a metric which is better than a second route to another gateway 19.226.129.7 which
would not have Tracking enabled. That route to the .7 would be the equivalent of a
floating static route coming into play when the tracking for .6 failed. Do I have this right?

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).
