You have implemented mutual route redistribution between OSPF and EIGRP on a border router.
When checking the routing table on one of the OSPF routers within the OSPF routing domain, you
are seeing some, but not all of the expected routes.
Which two things should you verify to troubleshoot this problem? (Choose two.)
A.
The border router is using a proper seed metric for OSPF.
B.
The border router is using a proper seed metric for EIGRP.
C.
The administrative distance is set for OSPF and EIGRP.
D.
The missing EIGRP routes are present in the routing table of the border router.
E.
The subnet keyword on the border router in the redistribute EIGRP command.
Explanation:
When troubleshooting EIGRP routes being distributed into OSPF, the first item to
check is that the missing EIGRP routes are in fact on the router performing the redistribution
(border router). If not, the routes cannot be redistributed into OSPF and troubleshooting should
occur within the EIGRP AS.
The second step is to verify that the subnets keyword has been appended to the redistribute eigrp
statement under the OSPF routing process. The question mentions that the networks being
redistributed are using a /28 mask, with implies that the networksare actually subnets not assigned
to classful boundaries.
OSPF will only redistribute classful networks by default. The keyword “subnets” allows subnets to
also be be redistributed into OSPF (not merely classful routes).
