Configuring OSPFv3 to Filter LSAs in an Area

Filtering LSAs in an area can prevent unnecessary LSA transmission. This reduces the size of the LSDB on the neighboring router and speeds up network convergence.

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 function is applicable only to the ABR.
