A classful distance vector
that uses ticks and hop count as its metric. RIP was based on a Xerox
protocol named GWINFO
and a later modification called routed
(pronounced "route-dee") was included with BSD
. RIP is an IGP
, so it routes in a single autonomous system
RIP 2 allows more info to be included in the packets and has a simple authentication mechanism.
RFC 1723 updates RFC 1058.
