Exam N10-009 topic 1 question 200 discussion

The static routes take precedence because they have the lowest administrative distance: Connected Interface: (0) - Directly connected networks are always preferred. Static Route: (0 or 1) EIGRP Summary Route: (5) External BGP (eBGP): (20) EIGRP (Enhanced Interior Gateway Routing Protocol): (90) IGRP (Interior Gateway Routing Protocol): (100) - Obsolete OSPF (Open Shortest Path First): (110) IS-IS (Intermediate System to Intermediate System): (115) RIP (Routing Information Protocol): (120) EIGRP External Route: (170) Internal BGP (iBGP): (200) Unknown: (255) - Unreachable routes

A static route typically takes precedence when building a routing table because it usually has a lower administrative distance (AD) compared to dynamically learned routes the router considers it a more reliable source of information and will use it first when choosing a path to a destination network; by default, static routes have an AD of 1, which is lower than most dynamic routing protocols, effectively prioritizing them in the routing table.
