When other routing protocol routes are being redistributed into OSPF, what is one of the most common problems?
Select the best response.
A.
missing the tag option in the redistribute command.
B.
missing the subnet option in the redistribute command.
C.
missing the metric option in the redistribute command.
D.
misconfiguring the metric-type option in the redistribute command to type-1.
E.
misconfiguring the metric-type option in the redistribute command to type-2.
Answer: B
Explanation
When pulling routes into OSPF, we need to use the keyword “subnets” so that subnets will be redistributed too. For example, if we redistribute these EIGRP routes into OSPF:
+ 10.0.0.0/8
+ 10.10.0.0/16
+ 10.10.1.0/24
without the keyword “subnets”
router ospf 1
redistribute eigrp 1
Then only 10.0.0.0/8 network will be redistributed because other routes are not classful routes, they are subnets. To redistribute subnets we must use the keyword “subnets”
router ospf 1
redistribute eigrp 1 subnets
-> B is correct.
