Abstract:
Systems and methods include obtaining a table having a plurality of addresses each having a plurality of attributes and classifications; responsive to a requirement to reduce a size of the table, reducing a number of the plurality of addresses based on one or more reduction approaches that use any of the plurality of attributes and classifications; and obtaining an output table having some or all of the plurality of addresses for a table receiver. The table can be obtained via control plane components including one or more of Interior Gateway Protocol (IGP) and Border Gateway Protocol (BGP). The requirement to reduce the size is based on a size of the table and a size of memory associated with the table receiver.
