Figure 80 depicts the format of attribute 26. The Vendor-ID field used to identify a
vendor occupies four bytes, where the first byte is 0, and the other three bytes are
defined in RFC 1700. Here, the vendor can encapsulate multiple customized
sub-attributes (containing vendor-specific Type, Length and Value) to implement a
RADIUS extension.
