What is the behavior of the default export policy for OSPF?

AAccept all routes.

BReject all routes.

CRedistribute all routes.

DForward all routes.

Show Suggested Answer

Suggested Answer: B

In Junos, the default export policy for OSPF is to reject all routes from being exported.

Step-by-Step Breakdown:

Default Export Policy:

By default, OSPF in Junos does not export any routes to other routing protocols or neighbors. This is a safety mechanism to prevent unintended route advertisements.

Custom Export Policies:

If you need to export routes, you must create a custom export policy that explicitly defines which routes to advertise.

Example: You can create an export policy to redistribute static or connected routes into OSPF.

Juniper Reference:

OSPF Export Behavior: In Juniper devices, the default policy for OSPF is to reject route advertisements unless explicitly configured otherwise through custom policies.

That's right, it forwards everything unless specified otherwise.

I’m leaning towards forward all routes, but I could be mixing it up with another protocol.

I feel like the answer might be to redistribute all routes, but that seems too broad for OSPF.

I've got a good feeling about this one. The default OSPF export policy is to redistribute all routes, if I remember correctly.

The wording of the question is a bit confusing. I'll read through the options carefully and try to eliminate the ones that don't sound right.

Hmm, I thought OSPF was all about finding the shortest path, not exporting routes. This seems like a trick question.
