  Consider the following:

  -Router R2 is an ABR in OSPF Areas 0 and 1.

  -

  Router R2 advertises the aggregate prefix 10.10.10.0/24 into Area 1.

  -

  Router R1 in Area 0 generates LDP labels for FECs 10.10.102/31 and 10.10.10.4/31

  A. Disable route summarization on router R3
  B. Enable LDP aggregate prefix match
  C. Create an import policy to accept these FECs
  D. Disable LDP exact match on the specified FECs
  B. Enable LDP aggregate prefix match
