Enabling Routing at the Module
The P580 and P882 have the option of centralized (unlicensed) or
distributed (licensed) routing function. When a module is licensed, the on-
board F-Chips (FIRE) provide the fast-path processing. When a module is
unlicensed, the fast path is handled by the single F-Chip (FORE) on the
Supervisor Module. Since the presence of an ACL will consume more F-
Chip memory, it is recommended to license all modules in a chassis. This
distributes the work load among more resources.
