  Router R2 advertises an OSPF summary route 10.10.10.0/24 into Area 1. Router R3 receives labels for individual FECs 10.10.10.2/32 and 10.10.10.4/32. These two FECs are installed in router R3's LIB but not in the LFIB. What needs to be done on router R3 to install these labels into its LFIB?

  A. Disable route summarization on router R3.
  B. Enable LDP aggregate prefix match.
  C. Create an import policy to accept 10.10.10.2/32 and 10.10.10.4/32.
  D. Disable LDP exact match on 10.10.10.2/32 and 10.10.10.4/32.
  B. Enable LDP aggregate prefix match.
