This is a read-write INTEGER letting an administrator set a new maximum for policy-based-routing rule entries in the Policy Route Table that only takes effect after the device's next reset, since the live table cannot be resized while running. Changing it lets an admin plan capacity ahead of a scheduled reboot rather than being limited to the currently active ceiling. For example, an admin adding rules to steer a new class of VoIP traffic raises this after-reset value before the next reload.
