• Question 568:

  Click on the exhibit button below:

  

  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
