IP Configuration: RIPv2
This section describes the Routing Information Protocol (RIP) version 2 feature.
NOTE The Sx500 models do not support the RIP Feature.
It covers the following topics:
• Overview
• How RIP Operates on the Device
• Configuring RIP
Overview
Routing Information Protocol (RIP) is an implementation of a distance-vector
protocol for local and wide-area networks. It classifies routers as either active or
passive (silent). Active routers advertise their routes to others; passive routers
listen and update their routes based on advertisements, but do not advertise.
Typically, routers run RIP in active mode, while hosts use passive mode.
The default gateway is a static route and it is advertised by RIP in the same way as
all other static routers, if it is enabled by configuration.
When IP Routing is enabled, RIP works fully. When IP Routing is disabled, RIP
works in the passive mode, meaning that it only learns routes from the received
RIP messages and does not send them.
NOTE The IP Routing control is available on the SG500X/ESW2-550X models only. To
enable IP Routing, go to Configuration > Management and IP Interface > IPv4
Interface page.
The device supports RIP version 2, which is based on the following standards:
• RFC2453 RIP Version 2, November 1998
• RFC2082 RIP-2 MD5 Authentication, January 1997
