You have implemented mutual route redistribution between OSPF and EIGRP on a border
router. When checking the routing table on one of the EIGRP routers within the EIGRP
routing domain, you are seeing some, but not all ofthe expected routes. What should you
verify to troubleshoot this problem? Select the best response.
A.
The border router is using a proper seed metric forOSPF.
B.
The border router is using a proper seed metric forEIGRP.
C.
The administrative distance is set for OSPF and EIGRP.
D.
The missing OSPF routes are present in the routing table of the border router.
E.
The subnet keyword on the border router in the redistribute OSPF command.
Explanation:
We are checking the routing table on EIGRP routers not OSPF so we don’t need to check
the seed metric for OSPF. Besides OSPF doesn’t needto specify seed metric as all
external routes get a default metric of 20 (except for BGP, which is 1) -> A is not correct.
We must specify seed metrics when redistributing into EIGRP (and RIP). If not all the
redistributed routes will not be seen but the question says only some routes are missing ->
B is not correct.
The default administrative distance for external routes redistributed into EIGRP is 170 so we
don’t need to set it -> C is not correct.
The sunbet keyword is only used when redistributinginto OSPF, not to other routing
protocols -> E is not correct.
We should check the routing table of the border router to see the missing OSPF routes are
there or not. An incorrect distribute-list can block some routes and we can’t see it in other
EIGRP routers -> D is correct.
