Overview of Software Packages
Package Installation Envelope Files
PIE files, are nonbootable files that can be used to upgrade a router or add software packages to the
router. A PIE may contain a single package or a set of packages (called a composite package). Because
the files are nonbootable, they must be installed and activated on a running router. PIE files have a .pie
extension. When a PIE file contains software for a specific bug fix, it is called a Software Maintenance
Update (SMU).
