One of the most widely used routing protocols in IP networks is the Routing Information Protocol(RIP)。 RIP is the canonical example of a  routing protocol built on the(请作答此空)algorithm.Routing protocols in internetworks differ slightly from the idealized graph model.In an internetwork, the goal of the routers to forward packets to various ( ).
Routers running RIP send their advertisement about cost every ( )  seconds.A router also sends an update message whenever an update from another router causes it to change its routing table.
It is possible to use a range of different metrics or costs for the links in a routing protocol.RIP takes the simplest approach, with all link costs being equal ( )。 Thus it always tries to find the minimum hop route.Valid distances are 1 through ( )。This also limits RIP to running on fairly small networks.
