Question # 6

If OSPF is used in a multi-area OSPF network, which of the following statements regarding route summarization is true?

Manual route summarization can only be done on autonomous system border routers.

Manual route summarization must be done on all the backbone routers to be effective. Manual route summarization is optional on the routers in non-backbone areas.

Manual route summarization is done on the ABRs. By default, automatic summarization is done; however, it may not be optimal for all networks.

Manual route summarization is done on the ABRs. By default, no route summarization is done and all routes are advertised to all areas.

The route table on router R2 shows the system address of router R5 but it does not show any of the interfaces from the non-OSPF area.

What may be causing this?

Router R1 needs to have an export policy added to it.

Router R5 does not have an export policy for these prefixes.

Router R1 needs to have an import policy added to it.
