Overview

One of the most widely used interior gateway protocols is the Routing Information Protocol (RIP). This implementation, designed from the ground up, includes all of the expected functionality, passes all of the industry test
suites (including ANVL and the UNH suites at the University of New Hampshire), and has seen great success in deployment.

The Green Hills GateD^® RIP implementation is fully compliant with RIPv1 (RFC 1058) and RIPv2 (RFC 2453). It supports CIDR/VLSN, tag setting and filtering, and simple password and MD5 authentication.

Beyond full support for the base RFCs, this cutting edge implementation has all of the features commonly requested by router vendors and their customers. This includes adjustable number of backup routes, hold-down timers ECMP, route redistribution, and much more.

Applications

The Green Hills RIP protocol is widely deployed in modest size networks in commercial, military, banking, and enterprise networks. RIP supports light weight dynamic routing across a variety of physical topologies such as Ethernet or serial links.

Green Hills RIP is ready for secure routing applications integrated with the Green Hills secure INTEGRITY operating system, flexible RIP sending policy, rich policy filters and TCP MD5 authentication per peer. RIP can operate as listen-only, send-only or send and receive routes. These settings (send-only, receive-only, send & receive) can be
set on a per interface basis.

GHS RIP contains an extensive policy engine that allows network operators to tailor RIP networks to specific network
connectivity and traffic patterns. With this policy engine, the network operator can restrict the routes passed in RIP, and thereby restrict the traffic patterns enabled by RIP routing. The Green Hills GateD policy engine supports network access lists, network prefix lists, and the TCP MD5 authentication is set on a per neighbor basis for IPv4 and IPv6 addresses.

Key Features

Green Hills RIP supports a full features RIP protocol implementation with an extensive policy suite. This full featured
implementation supports enhanced targeted route redistribution for advanced control of RIP routes, advanced RIP
routing features, and flexible routing timers.

The enhanced GateD RIP route distribution features have three types: protocol enhancements, policy filter enhancements, and route distribution capabilities. The GateD RIP supports the protocols ability to send routes on a per interface basis the listen-only mode (no-send command), send-only command (no-receive command), and send/
receive mode (normal mode).

The policy filter enhancements allow filter of routes based on interface, RIP peer, or the route prefix. The extensive
policy engine allows flexible combinations of filters on interface, peer, or routes (prefixes).

RIP may redistribute static and other dynamic routing protocols (OSPF, BGP).

Green Hills RIP also contains unique routing features to enhance the security of the RIP protocol by using Unicast transmission of RIP routing information. The source-gateway and trusted-gateway commands allow the complete control of what peers can send or receive information from GateD. This enhancement to allow unicast transmission
of RIP protocol traffic avoids broadcasting RIP routing information to a broadcast or multicast group.

Lastly, RIP provides the ability to allow flexible time periods for the RIP updates.

Key Benefits

GateD's RIP protocol implementation is ready for secure routing with TCP MD5, easily configurable send/receive functionality, unicast transmission of RIP protocol traffic , and an extensive policy engine.

This protocol implementation can support small deployments with listen-only RIP or larger deployments with full feature RIP. The extensive policy configurations language allows network operators the ability to control the traffic
during any period of group.

Supported Architectures

GateD’s platform independent scalable software has been ported, tested and validated on Green Hills secure INTEGRITY operating system and GHNet IPv4/v6 router stack, providing end customers with a complete, functional
single-vendor solution.
