Question

A router has two static routes to the same destination network within the same OSPF process. How are packets forwarded to that destination if the next-hop devices are different?

A The router chooses the route with the oldest age.
B The router chooses the next hop with the lowest IP address.
C The router chooses the next hop with the lowest MAC address.
D The router load-balances traffic over all routes to the destination.

Explanation

When a router has multiple routes to the same destination with equal preference and different next hops, it can install both routes in the routing table and use equal-cost multipath forwarding. That results in traffic being load-balanced across the available paths rather than selecting a path by route age, next-hop IP address, or MAC address.
