Overview

Manage the installation and configuration of Quagga (Routing Daemons) .

Module Description

This modules allows for the manging of the quagga BGP daemon. Other routing modules are currently unsupported however you should be able to configure them manuly

Setup

What quagga affects

  • Manages the quagga configueration file
  • Manages the quagga bgpd configueration file
  • can export nagios_service to test neighbours are Established and routes are being advertised

Setup Requirements

  • depends on stdlib 4.11.0 (may work with earlier versions)

Beginning with quagga

Install the package an make sure it is enabled and running with default options, this will just configure zebra to run with no bgp config:

class { '::quagga': }

With some bgp peers

class { '::quagga': }
class { '::quagga::bgpd':
  my_asn => 64496,
  router_id => '192.0.2.1',
  networks4 => [ '192.0.2.0/24'],
  peers => {
    '64497' => {
      'addr4' => ['192.0.2.2'],
      'desc'  => 'TEST Network'
    }
  }
}  

and in hiera

my_asn: 64496,
router_id: 192.0.2.1
networks4:
- '192.0.2.0/24'
peers:
  64497:
    addr4:
    - '192.0.2.2'
    desc: TEST Network

Usage

Add config but disable advertisments and add nagios checks

class { '::quagga::bgpd':
  my_asn => 64496,
  router_id => '192.0.2.1',
  networks4 => [ '192.0.2.0/24'],
  enable_advertisements => false,
  peers => {
    '64497' => {
      'addr4' => ['192.0.2.2'],
      'desc'  => 'TEST Network'
    }
  }
}  

Full config

class { '::quagga::bgpd':
  my_asn                   => 64496,
  router_id                => '192.0.2.1',
  networks4                => [ '192.0.2.0/24', '10.0.0.0/24'],
  failsafe_networks4       => ['10.0.0.0/23'],
  networks6                => ['2001:DB8::/48'],
  failsafe_networks6       => ['2001:DB8::/32'],
  enable_advertisements    => false,
  enable_advertisements_v4 => false,
  enable_advertisements_v6 => false,
  manage_nagios            => true,
  peers => {
    '64497' => {
      'addr4'          => ['192.0.2.2'],
      'addr6'          => ['2001:DB8::2'],
      'desc'           => 'TEST Network',
      'inbound_routes' => 'all',
      'communities'    => ['no-export', '64497:100' ],
      'multihop'       => 5,
      'password'       => 'password',
      'prepend'        => 3,
    }
  }
}  

Reference

Classes

Public Classes

Class: quagga

Guides the basic setup and installation of Quagga on your system

Parameters (all optional)
  • owner (String, Default: quagga): User to use for permissions
  • group (String, Default: quagga): Group to use for permissions
  • mode (String /^\d+$/, Default: 0664): Mode to use for permissions
  • quagga_content (String, Default: 'hostname ${::fqdn}'): content of the quagga config
  • enable_zebra (Bool, Default: true): determin if we should enable zebra
  • package (String, Default: quagga): package to install

Class: quagga::bgpd

configure BGP settings

Parameters (all optional)
  • my_asn (Int, Default: undef): The local ASN to use
  • router_id (IP Address, Default: undef): IP address for the router ID
  • networks4 (Array, Default: []): Array ip IPv4 networks in CIDR format to configure
  • failsafe_networks4 (Array, Default: []): Array ip IPv4 failsafe networks in CIDR format to configure. Failsafe networks consist of covering prefixes for the IPv4 networks. if the policy decided to disable advertising due to detected errors it will leave the failsafe network inplace. This is a specific use case for anycast networks which effectivly disables an anycast node as all others will still be advertising a more specific network; however if something goes wrong and all nodes have the most specific route removed then we would still have this failsafe network in place.
  • networks6 (Array, Default: []): Array ip IPv6 networks in CIDR format to configure
  • failsafe_networks4 (Array, Default: []): Array ip IPv6 failsafe networks in CIDR format to configure. See failsafe_networks4 for a description
  • failsafe_server (Bool, Default: false): If this is set to true then we will only ever advertise the failsafe networks. i.e. the node will be effectivly ofline unless all other nodes are either out of commision or remove ther most specific networks (networks4 and networks6)
  • enable_advertisements (Bool, Default: true): If this is set to false then no networks, including the failsafe networks, will be advertised.
  • enable_advertisements_v4 (Bool, Default: true): If this is set to false then no IPv4 networks, including the failsafe IPv4 networks, will be advertised.
  • enable_advertisements_v6 (Bool, Default: true): If this is set to false then no IPv6 networks, including the failsafe IPv6 networks, will be advertised.
  • manage_nagios (Bool, Default: false): If this is set to true the policy will create vertual resources to check each peer neighbor'
  • conf_file (Absolute file path, Default: '/etc/quagga/bgpd.conf'): The fully qualified path to the managed config file

  • logrotate_size (String, Default: 100M): The String size a log file has to reach before it will be rotated. The default units are bytes, append k, M or G for kilobytes, megabytes or gigabytes respectively.
  • log_syslog (Bool, Default: false): if set to true enable logging to syslog
  • log_syslog_facility (String, Default: 'daemon') The syslog facilty to use

  • log_monitor (Bool, Default: false): if set to true enable logging to monitor
  • log_monitor_level (Valid Logging level, Default: debugging): The logging level for monitor logging
  • log_record_priority (Bool, Default: false): If true log the severity in all messages logged to a file, to stdout, or to a terminal monitor (i.e. anything except syslog)
