• Question 6:

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

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