Introduction
xxvii
Chapter 3 covers VLANs--how they work and how to configure them
in a Cisco internetwork. Trunking and VLAN Trunk Protocol (VTP)
will be described and implemented.
Chapter 4 will give you an in-depth look at the Spanning Tree Proto-
col (STP), its timers, and how to configure STP in a switch.
Chapter 5 shows you how to configure STP timers and includes a
discussion of root bridge selection. Redundant links with STP will
also be covered.
Chapter 6 covers Inter-Switch Link (ISL) routing. Both internal route
processors and external route processors are covered, as well as how
to configure both internal and external route processors to connect
multiple VLANs.
Chapter 7 will provide the fundamentals of multi-layer switching on
both internal and external route processors. In addition to covering IP
routing with MLS, we'll show you how to configure the MLS engine.
Chapter 8 gives you an extensive discussion of Hot Standby Routing
Protocol (HSRP). The chapter provides HSRP as a solution to IP
default gateway issues. Configuring HSRP is also covered.
Chapter 9 covers the background of multicast addresses and how to
translate from a layer 3 address to a layer 2 multicast address. Chapter 9
also covers IGMP and CGMP.
Chapter 10 is about configuring multicast in a Cisco internetwork.
Enabling multicast, joining a multicast group, and enabling CGMP
are also covered.
Chapter 11 ends this book by talking about access policies, how to
create them, and how to implement them.
Appendix A is a practice exam (see "How to Use This Book" later in
this introduction for more on the practice exam).
Appendix B includes all of the commands used in this book along with
explanations of each command and how they are used with both
access layer and distribution layer switches.
Appendix C is a list of all multicast addresses as listed in RFC 1112.
It also includes a list of all the assigned multicast addresses.
