Foundation Summary 419
Table 6-23 and Table 6-24 summarize the more popular commands used for RIP and IGRP
configuration and verification.
RIP-2, defined by RFC 1723, is simply an improved version of RIP Version 1. Many features
are the same: Hop count is still used for the metric, it is still a distance vector protocol, and it
still uses holddown timers and route poisoning. Several features have been added; the features
are listed in Table 6-25.

each route so that the subnet is exactly defined.
