DN Bit
The previously unused bit in the OSPF LSA Options Field is referred to as the DN Bit. This bit is set on Type 3, 5, and 7 LSA when the MP-BGP routes are redistributed into OSPF. When the other PE Router receives the LSA from a CE router Type 3, 5, or 7 LSA with the DN Bit set, the information from that LSA is not used in the OSPF route calculation.
