This is a read-write INTEGER letting an administrator set a new maximum for RP addresses allowed per multicast group range in the RPSet 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 a fifth backup RP for a group range must first raise this after-reset limit before the next device reset.
