By default, which statement is correct regarding the redistribution of routes from other
routing protocols into OSPF?
A.
They will appear in the OSPF routing table as type E1 routes.
B.
They will appear in the OSPF routing table as type E2 routes.
C.
Summarized routes are not accepted.
D.
All imported routes will be automatically summarized when possible.
E.
Only routes with lower administrative distances will be imported.
Explanation:
Type E1 external routes calculate the cost by adding the external cost to the internal cost of
each link that the packet crosses while the external cost of E2 packet routes is always the
external cost only. E2 is useful if you do not want internal routing to determine the path. E1 is
useful when internal routing should be included in path selection. E2 is the default external
metric when redistributing routes from other routing protocols into OSPF.
