12.3 RIP
12.3.1 Key elements of RIP
RIP was originally specified in RFC 1058. Its key characteristics include the following:
  • It is a distance-vector routing protocol.
  • Hop count is used as the metric for path selection.
  • If the hop count is greater than 15, the packet will be discarded.
  • By default, routing updates are broadcast every 30 seconds.
