R1 and R2 are ASBRs in the same area, each with an equal cost external path to the same
external network prefix. R1 advertises an external route into OSPF with a Type 1 metric. R2
advertises an external route into OSPF with a Type 2 metric. Which route would be
preferred?
A.
R1’s route is preferred because Type 1 metrics take into account the external cost only.
B.
R1’s route is preferred because Type 1 metrics take into account the internal and
external cost.
C.
R2’s route is preferred because Type 2 metrics take into account the internal and
external cost.
D.
R2’s route is preferred because Type 2 metrics take into account the external cost only.
B, type 1 is prefered.
D:By default, the Junos OS marks these LSAs with the type 2 designation, which means the cost of the associated OSPF route is not added. You can alter this default behavior and mark these external prefixes with the type 1 designation, which means the cost to the ASBR will be included. External LSAs are flooded to all OSPF areas except areas defined as stub areas.
B is the closest answer to being correct. Type-1 prefixes are always preferred over the same prefix via Type-2 regardless of costs.
