How-to : Adding devices to RANCID

-

Some time ago I described How to : Install RANCID on openSUSE 11.4 “Celadon”. However, just after installation RANCID will do nothing without proper configuration.

So, in this lab I will show how to:

  • create group of devices in rancid
  • add information about credentals to RANCID
  • add 2 Cisco routers to that group
  • collect configuration from routers
  • setup cron task to run rancid automatically

Systems which will be used to demonstrate how to add device to RANCID and collect configuration:

  • lab-gw-01 – IP: 172.16.90.5 – openSUSE witn RANCID – installed on VMware Workstation
  • lab-r1 – IP: 172.16.90.123 – Cisco router – started on GNS3
  • lab-r2 – IP: 172.16.90.124 – Cisco router – started on GNS3

How-to : RANCID installation on openSUSE 11.4 “Celadon”

RANCID is a great automation tool which allows you to collect configuration from network devices and store in repository with version control (CVS or SVN). In this article I will show you how to install RANCID and prepare to work on openSUSE 11.4 with subversion as repository for configs.

Having repository with network devices configuration might be also part of disaster recovery planning as in case of failure it will be easy to pull recent configuration from repository and apply on replacement router or switch.

To demonstrate commands I’m using copy&paste from PuTTY while executing step-by-step what is described in this article.
