The path cost metric utilized by the Routing Information Protocol (RIP) to evaluate route preference is:
Multiple Choice Options
- A
Bandwidth
- B
Delay
- C✓ Correct Option
Hop count
- D
Reliability
Detailed Technical Solution & Explanation
The Routing Information Protocol (RIP, RFC 1058 / RFC 2453) is a distance-vector routing protocol that uses hop count as its exclusive routing metric. Each router traversed between source and destination increments the metric by 1. RIP does not account for link bandwidth, delay, or reliability, always favoring a path with fewer intermediate routers even if those links are significantly slower.
Option Analysis:
•
Option A (Bandwidth): Incorrect; used by OSPF (cost = reference bandwidth / link bandwidth) and EIGRP.
•
Option B (Delay): Incorrect; used in composite metric calculations by EIGRP.
•
Option C (Hop count): Correct; RIP relies solely on the integer number of router hops (from 0 to 15).
•
Option D (Reliability): Incorrect; optional parameter in EIGRP composite metric.
