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
Router R3 in Area 1 places these FECs in its LIB, but it does not place them in its LFIB. What can you do on router R3 to make it populate these labels in its LFIB?
