RIP
Note
：
Router mentioned in this chapter refers to the traditional router or the switch running routing
protocols.
RIP (Routing Information Protocol) is intended for use within the IP-based Internet. This
protocol is most useful as an Interior Gateway Protocol (IGP). RIP was designed to work with
moderate-size networks using reasonably homogeneous technology. Thus it is suitable as an
IGP for many campuses and for regional networks using serial lines whose speeds do not vary
widely. It is not intended for use in more complex environments.
RIP is a distance vector routing protocol, using UDP packets for exchanging information
through port 520.
RIP uses “hop” to measure the distance to a destination. The hop count from a router to a
directly connected network is 0. The hop count from a router to a directly connected router is 1.
To limit convergence time, the range of RIP metric value is from 0 to 15. A metric value of 16 (or
greater) is considered infinite, which means the destination network is unreachable. That is why
RIP is not suitable for large-scaled networks.
RIP prevents routing loops by implementing the split horizon and poison reverse functions.

RIP routing table
An RIP router has a routing table containing routing entries of all reachable destinations, and
each routing entry contains:

Destination address: IP address of a host or a network.

Next hop: IP address of the adjacent router’s interface to reach the destination.

Egress interface: Packet outgoing interface.

Metric: Cost from the local router to the destination.

Route time: Time elapsed since the routing entry was last updated. The time is reset to
0 every time the routing entry is updated.
