Abstract
Methods and apparatus to selectively assign routing tables to router linecards are disclosed. A disclosed example method includes computing costs associated with assigning routing information for two or more subsets of virtual private networks (VPNs) to each of two or more subsets of linecards of a router, solving an incapacitated facility location problem defined by the computed costs to determine an assignment of a particular subset of the VPNs to a particular subset of the linecards of the router, and configuring the particular subset of the linecards of the router with routing information for the particular subset of the VPNs.
