Security 689
Over the years, the CCIE program has expanded to add several CCIE certifications besides the
Routing and Switching track. As a result, some topics previously covered in the Routing and
Switching exam have been removed, or shortened, because they are more appropriate for
another CCIE track. For example, the CCIE Routing and Switching track formerly covered
voice to some degree, but the CCIE Voice track now covers voice to a much deeper level.
The topics in this chapter are certainly covered in more detail in the CCIE Security written and
lab exams. However, because security has such an important role in networks, and because
many security features relate specifically to router and switch operations, some security details
remain within the CCIE Routing and Switching track. This chapter covers many of the core
security features related to routers and switches.
