Routing Information Protocol (RIP)
The Routing Information Protocol (RIP) tracks distances or hop counts to nearby routers when establishing
network connections and is based on a distance-vector algorithm.
RIP is based on a distance-vector algorithm; it tracks distances or hop counts to nearby routers when
establishing network connections.
RIP protocol standards are listed in the Standards Compliance chapter.

Protocol Overview
RIP is the oldest interior gateway protocol.
There are two versions of RIP: RIP version 1 (RIPv1) and RIP version 2 (RIPv2). These versions are documented
in RFCs 1058 and 2453.
RIPv1
RIPv1 learns where nodes in a network are located by automatically constructing a routing data table.
The routing table is established after RIP sends out one or more broadcast signals to all adjacent nodes in a
network. Hop counts of these signals are tracked and entered into the routing table, which defines where
nodes in the network are located.
The information that is used to update the routing table is sent as either a request or response message. In
RIPv1, automatic updates to the routing table are performed as either one-time requests or periodic
responses (every 30 seconds). RIP transports its responses or requests by means of user datagram protocol
(UDP) over port 520.
RIP must receive regular routing updates to maintain a correct routing table. Response messages containing a
router’s full routing table are transmitted every 30 seconds. If a router does not send an update within a
certain amount of time, the hop count to that route is changed to unreachable (a route hop metric of 16
hops). Another timer sets the amount of time before the unreachable routes are removed from the routing
table.
