Show AnswerHide Answer
Correct Answer: B
In EIGRP, split horizon is a mechanism that prevents routing loops by prohibiting a router from advertising a route back onto the interface from which it was learned. In a multipoint interface, this feature can prevent traffic from passing correctly because routes that need to be transmitted through the same interface won't be advertised correctly. Disabling split horizon on the multipoint interface will allow these routes to be advertised and enable proper traffic flow.

Feb 1, 2023When split horizon is enabled, any route learned from an interface is not advertised back out the same interface. This rule is intended to stop routing loops with distance-vector protocols.
