Junoser

Junoser is a JUNOS configuration PEG parser which can be automatically generated from Juniper's netconf.xsd. (XML Schema Definition for NETCONF)

Features

• Configuration Validation

  • Structured "show configuration" format
  • One-liner "| display set" format

• Configuration Translation

  • Inter-translation between structured form and display-set form

NOTE

Inter-translation from display-set form into structured form is experimental feature in this release.

Getting Started

$ gem install junoser

Usage

To verify configurations syntax:

$ junoser -c config.txt

or

$ cat config.txt | junoser -c

To translate configuration into "display set" form:

$ /exe/junoser -d config.txt
set protocols bgp group ebgp-peers neighbor 192.0.2.2

or

$ cat config.txt | junoser -d
set protocols bgp group ebgp-peers neighbor 192.0.2.2

Use junoser -s to translate into structured form.

Updating parser for new directives

From Juniper website, you can download the XSD schema for the version of JunOS you want to target:

• Junos XML API
• Select your version
• Application Tools
• XML Schema for Configurator Data

Alternatively, you can retrieve the schema with Netconf:

$ ssh -Csp 830 JUNOS netconf < example/get-schema.xml | sed -n '/^<xsd:schema/,/^<\/xsd:schema/p' > junos-XXX.xsd

Put it in tmp/, update xsd_path in Rakefile and run:

$ bundle exec rake build:config build:rule

Alternatively, you may look in example/ for some prebuilt rules file. If you want to use them, copy one to tmp/rules.rb and run:

$ bundle exec rake build:rule
