Summary

This chapter reviewed the overall operational and business benefits of having a fully ISSU-capable routing system. The chapter also used detailed examples and command snapshots to explain the intricacies of ISSU for a 6RU system running either a consolidated package or subpackages, the latter of which essentially results in a more controlled upgrade in a granular fashion.

The next few chapters look at ASR 1000 system management and troubleshooting.
