Exam 300-101 topic 2 question 569 discussion

Actual exam question from Cisco's 300-101

Question #: 569
Topic #: 2

Refer to the exhibit.

EIGRP has been configured on router D. Router C is performing mutual redistribution between EIGRP 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 of the problem?

A. The no auto-summary command needs to be added under router eigrp 1.
B. The subnets keyword was not included in the redistribute command under router ospf 1.
C. The metric specified for the redistributed EIGRP routes is too large; making the EIGRP routes unreachable by router A.
D. The default-information originate command needs to be added under router ospf 1.

Show Suggested Answer

Suggested Answer: E. The administrative distance of either OSPF or EIGRP must be changed so that EIGRP has a higher administrative distance than OSPF. 🗳️
Explanation -
If we don`t use the subnets keyword when redistributing routes learned from another routing process into OSPF, only classful routes will be redistributed. This is an important thing to remember when redistributing into OSPF.

B. There is a flapping link or interface, and router C knows an alternate path to the network.
