A router has EIGRP configured as the only routing protocol. How does EIGRP respond if there is no feasible successor route to a destination network and the successor route fails?（）

• A、It immediately sends its entire routing table to its neighbors.
• B、EIGRP sends a Hello packet to the DR to inform it of the route failure.
• C、It automatically forwards traffic to a fallback default route until a successor route is found.
• D、It sends queries out to neighbors until a new successor route is found.
• E、It places the route in holddown until LSA updates inform it of a new route to the network.
