Overview
The Border Gateway Protocol (BGP) provides loop-free interdomain routing between
autonomous systems (ASs). This section describes some of the main concepts of BGP.
Conventions in This Chapter
Certain terms used with BGP, such as the names of attributes and messages, are typically
expressed in all uppercase letters in the RFCs. For improved readability, those terms are
represented in lowercase in this chapter. Table 3 on page 4 lists the terms and their
variant spellings.
