Interface Descriptor Blocks

[mike_lucci]

I am looking for information on Interface Descriptor Blocks relative to how they relate to memory allocation. Specifically, why it is a good practice to reboot a router should a significant number of sub-interfaces be deleted via the "no interface" command.
