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.

Refer to the exhibit. EIGRP has been configured on router D. Router C is performing mutual redistribution between EI GRP and OSPF. While verifying that the redistribution is functioning properly, you discover that while router C has all of the EIGRP routes in its routing table, router A does not have any routes from the EIGRP domain. What on router C may be the cause o f the problem?（）A. The no auto - summary command needs to be added under router eigrp 1B. The subnets keyword was not included in the redistribute command under router ospf 1C. The metric specified for the redistributed EIGRP routes is too large; m aking the EIGRP routes unreachable by router AD. The default - information originate command needs to be added under router ospf 1E. The administrative distance of either OSPF or EIGRP must be changed so that EIGRP has a higher administrative distanc e than OSPF

Refer to the exhibit. EIGRP has been configured on routers R1 and R2. However, R1 does not show R2 as a neighbor and does not accept routing updates from R2.What could be the cause of the problem?()

EIGRP cannot exchange routing updates with a neighbor‘s router interface that is configured with tw o IP addresses.D. EIGRP cannot form neighbor relationship and exchange routing updates with a secondary address.
