Enhanced Routing Protocol Support (RIPng Next generation IPv6)

By | December 21, 2013

RIPng is One of the most widely used interior gateway protocols is the Routing Information Protocol (RIP). RIPng (Routing Information Protocol – next generation) is an IPv6 implementation of this distance-vector, or Bellman-Ford, routing protocol for local networks. RIPng is based on the RIP protocol and inherits the limitations and constraints that are in RIP.

This RIPng functionality includes a separate RIB for the IPv6 address family, ICMP for IPv6, and IPv6 neighbor discovery.

The IPv6 family of protocols strikes the perfect balance between richness of features and the safety of deployed code that’s working in the Internet today.  And like the IPv4 unicast routing protocols, all of the IPv6 protocols are fully tested for conformance and interoperability. RIPng supports a full featured RIPng protocol implementation with an extensive policy suite. This full featured implementation supports enhanced targeted route redistribution for advanced control of RIPng routes, advanced RIPng routing features, and flexible routing timers.

RIPng route distribution features have three types: protocol enhancements, policy filter enhancements, and route distribution capabilities. RIPng supports the protocols’ ability to send routes on a per interface basis in the listen-only mode (no-send command), send-only command (noreceive command), and send/receive mode (normal mode). The policy filter enhancements allow filter of routes based on interface, RIPng peer, or the route prefix. The extensive policy engine allows flexible combinations of filters on interface, peer, or routes (prefixes).

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

  • Similar characteristics as IPv4
  1. Distance-vector, hop limit of 15, split-horizon, multicast based (FF02::9), UDP port (521) etc.
  • Updated features for IPv6
  1. IPv6 prefix & prefix len
  • Special Handling for the NH
  1. Route tag and prefix len for NH is all 0. Metric will have 0xFF; NH must be link local

Key Benefits of RIPng

RIPng protocol implementation is ready for secure routing with TCP MD5, easily configurable send/receive functionality, Unicast transmission of RIPng protocol traffic, and an extensive policy engine.

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