Refer to the exhibit. Two-way redistribution was configured between OSPF and EIGRP on R2. After the redistribution, R3 does not see any external routes coming from the EIGRP domain. The debug ip ospf database external output reveals that no external LSAs are generated for the routes. What could be the problem?

Question:

Refer to the exhibit. Two-way redistribution was configured between OSPF and EIGRP on R2. After the redistribution, R3 does not see any external routes coming from the EIGRP domain. The debug ip ospf database external output reveals that no external LSAs are generated for the routes. What could be the problem?

• A default-metric command is missing from the EIGRP configuration.
• A distribute list is needed for both OSPF and EIGRP.
• An area 0 stub command is missing from the OSPF configuration.
• A subnet keyword is missing from the OSPF configuration.

Explanation: When redistributing into OSPF, if the optional subnets keyword is not included, only classful networks are redistributed.
