IP Routing Administrative Distances & Metrics

A static route does have an Administrative Distance and by default it is 1 and can be set to some different value. Metrics are used by dynamic routing ...

The metric value of the static routes is 0, and it will not change if you set the static route with the next hop or the exit interface.

Floating static routes are static routes with a higher administrative distance, you can use them as a backup for other routes with a lower AD.

Metric is the measure used to decide which route is better (a lower number is better). Each routing protocol uses its own metric.

Since static routes have a lower AD than any of the dynamic routing protocols they will always be preferred over routes for same destination network learned ...

Setting static routing on Cisco Layer 3 device is the fastest way to achieve communication in routed IP networks.

例如加入一條AD 50 的Static Route。 至於Metric 的比較則複雜一點，建議參考各Routing Protocol 的教學。
