Cisco CCNA (200-301)IP ConnectivityEasy
A network administrator configures a static route on a Cisco router using the command `ip route 192.168.10.0 255.255.255.0 10.0.0.2`. What is the administrative distance of this route?
- A110
- B1
- C0
- D120
Show answer & explanationAnswer & explanation
Correct answer: B. 1
Static routes configured with a next-hop IP address, but without an explicitly defined administrative distance, default to an administrative distance of 1. This makes them highly preferred routes.
Why the other options are wrong
- A. 110 is the default administrative distance for OSPF routes.
- C. An administrative distance of 0 is reserved for directly connected interfaces.
- D. 120 is the default administrative distance for RIP routes.
Static Route Administrative Distance
The default administrative distance for a user-defined static route in Cisco IOS is 1, indicating its trustworthiness and preference in the routing table.
- Default AD for static routes (with next-hop IP) is 1.
- Can be manually changed using 'ip route ... <AD>' command.
- Lower AD is preferred over higher AD.
Memory trick: AD: Always Decide which path is best!
