Mobile IP Administration Guide


The Mobile IP Administration Guide provides information about configuring and managing the Mobile IP framework installed in your SolarisTM operating environment. This book assumes that you have already installed the SunOSTM 5.8 operating system, and you have set up any networking software that you plan to use. The SunOS 5.8 operating system is part of the Solaris product family, which includes the Solaris Common Desktop Environment (CDE). The SunOS 5.8 operating system is compliant with AT&T's Unix\256 System V, Release 4 operating system.

Note -

The Solaris operating environment runs on two types of hardware, or platforms: SPARCTM and IA. The Solaris operating environment runs on both 64-bit and 32-bit address spaces. The information in this document pertains to both platforms and address spaces unless called out in a special chapter, section, note, bullet, figure, table, example, or code example.

Who Should Use This Book

This book is intended for anyone who administers one or more systems that run the Solaris 8 release. To use this book, you should have one to two years of UNIX\256 system administration experience. Attending UNIX system administration training courses might be helpful, if you lack the experience.
