What does RIPv2 use to prevent routing loops?
1. CIDR
2. Split horizon
3. Authentication
4. Classless masking
5. Holddown timers

Answer & Solution
Correct Answer: Option C
RIPv2 uses the same timers and loop-avoidance schemes as RIPv1. Split horizon is used to stop an update from being sent out the same interface it was received on. Holddown timers allow time for a network to become stable in the case of a flapping link.
