Routing Information Protocol

Routing Information Protocol (RIP) is one of the protocols which may be used by routers to exchange network topology information. It is characterized as an “interior” gateway protocol, and is typically used in small to medium-sized networks.

RIP Configuration

A router running RIP will send the contents of its routing table to each of its adjacent routers every 30 seconds. When a route is removed from the routing table it will be flagged as unusable by the receiving routers after 180 seconds, and removed from their tables after an additional 120 seconds.

There are two versions of RIP:

RIPv1 defined in RFC 1058

Routes are specified by IP destination network and hop count

The routing table is broadcast to all stations on the attached network

RIPv2 defined in RFC 1723

Route specification is extended to include subnet mask and gateway

The routing table is sent to a multicast address, reducing network traffic

An authentication method is used for security

The 7000 Series Managed Switch supports both versions of RIP. You may configure a given port:

To receive packets in either or both formats

To transmit packets formatted for RIPv1 or RIPv2 or to send RIPv2 packets to the RIPv1 broadcast address

To prevent any RIP packets from being received
