In the Routing Information Protocol (RIP), a hop count value of 16 indicates that the target destination network is:
In the Routing Information Protocol (RIP), a hop count value of 16 indicates that the target destination network is:
Multiple Choice Options
- A
Optimal
- B✓ Correct Option
Unreachable (infinity)
- C
Preferred
- D
Temporarily down
Detailed Technical Solution & Explanation
To prevent infinite routing loops caused by the count-to-infinity problem in distance-vector protocols, RIP defines an upper boundary metric for infinity. The maximum allowable metric for a valid reachable route is 15 hops. A metric value of 16 represents infinity, formally designating the destination network as unreachable.
Option Analysis:
•
Option A (Optimal): Incorrect; lower hop counts (e.g., 1 or 2) are optimal.
•
Option B (Unreachable (infinity)): Correct; hop count of 16 defines infinity/unreachability in RIP.
•
Option C (Preferred): Incorrect; routes with metric 16 are purged from active forwarding tables.
•
Option D (Temporarily down): Incorrect; RIP treats 16 as completely unreachable, triggering poison reverse.
