Cisco IOS Software Packaging
Cisco is migrating to using Cisco IOS Packaging to simplify the image-selection process by consolidating the total number of packages and using consistent package names across all hardware products. Figure 5-22 illustrates the various packages available with Cisco IOS packaging.

Four packages have been designed to satisfy the requirements in base service categories; they are as follows:
■ IP Base: Supports IP data
■ IP Voice: Supports converged voice and data
■ Advanced Security: Provides security and VPN
■ Enterprise Base: Provides enterprise Layer 3 protocols and IBM support
NOTE The features of the lower-tier packages are included in the higher-tier packages.
Three additional premium packages offer new Cisco IOS Software feature combinations that address more complex network requirements:
■ SP Services: Adds SP features, including MPLS, ATM, Secure Shell (SSH) and NetFlow, to the IP Voice package
■ Advanced IP Services: Adds advanced SP services to the Advanced Security package
■ Enterprise Services: Adds advanced SP services to the Enterprise Base package
Advanced Enterprise Services, which integrates support for all routing protocols with voice, security, and VPN capabilities, includes all the features of the other packages.
NOTE Cisco IOS Packaging is available for Cisco IOS Release 12.3 on some Cisco Integrated Services Routers (ISR). Most Cisco access, distribution or aggregation, and core routers, and other hardware that runs Cisco IOS software, will support Cisco IOS Packaging in the future.
After a feature is introduced, it is also included in the more comprehensive packages. Cisco calls this the feature inheritance principle of Cisco IOS Packaging; it provides clear migration, clarifying the feature content of the various packages and how they relate to one another.
