Technology Review
The RIP protocol is based on the Bellham-Ford (distance-vector) algorithm. This algorithm provides that a
network will converge to the correct set of shortest routes in a finite amount of time, provided that:
Gateways continuously update their estimates of ro utes.
Updates are not overly delayed and are made on a regular basis.
The radius of the networ k is not excessive.
No further topo logy ch an ge s take place .
RIP is described in RFC 1058 (Version 1) and updated in RFCs 1721, 1722, and 1723 for Version 2.
Version 2 includes components that ease compatibility in networks operating with RIP V1.
All advertisements occur on regular intervals (every 30 seconds). Normally, a route that is not updated for
180 seconds is considered dead. If no other update occurs in the next 60 seconds for a new and better
route, the route is flushed after 240 seconds. Consider a connected route (one on a local interface). If the
interface fails, an update is immediately triggered for that route only (advertised with a metric of 16).
