RIPv2/RIPng Configuration Module

This configuration module configures the RIPv2 and RIPng. The module supports the following RIP features:

  • IPv4 and IPv6

  • Passive interfaces

  • VRF RIPv2/RIPng instances

Lab Topology Parameters

You can change the RIPv2/RIPng timers with the global rip.timers dictionary (more details).

The RIPv2/RIPng configuration module supports these node parameters:

  • rip.timers: Change RIP timers for a single node

  • ripv2.import: Specify the import (redistribution) of routes into the global RIP instance (default: no route import).

RIPv2 also supports Passive Interfaces and External Interfaces.

VRF Parameters

  • By default, netlab redistributes BGP- and connected routes into VRF RIPv2/RIPng instances on all network devices. You can change that on devices supporting configurable route import with the ripv2.import VRF parameter.

  • Use rip.timers VRF parameter to change RIP timers for a single VRF instance

  • Set ripv2.active to True to force a VRF to use RIPv2/RIPng even when no routers are attached to the VRF interfaces.

  • To disable RIPv2/RIPng in a VRF set ripv2 to False (see also Disabling a Routing Protocol in VRF).

Changing RIP Timers

You can change the RIP protocol timers with the rip.timers global/node/VRF dictionary. The dictionary has these elements:

  • update: periodic RIP update timer. Default: 30 seconds, minimum: 5 seconds

  • timeout: route expiration timer. Default: six times the update timer, minimum: 5 seconds)

  • garbage: garbage collection timer (the time after which an invalid route is removed from the routing table). Default: four times the update timer, minimum: 5 seconds

Example

We want to create a simple two-router RIPv2 network using Cumulus Linux:

defaults.device: cumulus
module: [ ripv2 ]

The lab has two nodes and a link between them:

nodes: [ r1, r2 ]
links: [ r1-r2 ]

This is the resulting RIPv2 FRRouting configuration for R1:
