When "ip ospf network point-to-multipoint delayed-reflooding" is configured, LSAs received on an OSPF P2MP network are not reflooded. Since LSA reflooding would normally serve as an implied LSA acknowledgment, an explicit OSPF ack should be sent to avoid retransmission by the neighbor which orginally flooded the LSA on the P2MP network.
