In this episode you will learn:

- Administrative Distance (AD) is the first tie-breaker, determining the trustworthiness of a routing protocol (lower is better).

- Metric is the second tie-breaker, used to find the best path *within* a single routing protocol.

- A router will always prefer a route with a lower AD, regardless of the metric.

- Key default AD values to memorize: Connected (0), Static (1), EIGRP (90), OSPF (110), RIP (120).

- The mnemonic "Every Old Router" helps recall the AD values for EIGRP (90), OSPF (110), and RIP (120).
