(Optional) Configuring OSPFv3 to Filter LSAs in an Area
Context
After filtering conditions are set for the incoming or outgoing Type 3 LSAs (Inter-Area-Prefix LSAs) in an area, only the Type 3 LSAs that meet the filtering conditions can be received or advertised. This filters unnecessary LSAs, reduces the LSDB size, and increases network convergence.
This function is applicable only to the ABR.
