Which outcome occurs when a network router's path selection uses a distance-vector routing algorithm with poisoned reverse?

A)Faster convergence for all routes
B)Increased computational overhead on routers
C)Unstable routing for distant neighbors
D)Prevention of two-node count-to-infinity problems

💡 Explanation

A poisoned reverse path selection algorithm prevents two-node count-to-infinity problems because a router advertises a route to a neighbor as unreachable if that neighbor is its next hop for that route. Therefore, the instability is avoided, rather than occurring, and better path determination results than simple distance vector routing.
