Summary:
The Juniper Networks IOS-to-JUNOS (I2J) Conversion  (I2J) Tool is a software configuration translator that converts Cisco IOS to Juniper Networks JUNOS Software full IOS Configuration files for Cisco 65xx, 75xx and 12xxx platforms into Juniper Networks JUNOS format).  The I2J Conversion Tool is available to all Juniper customers and partners with a valid support contract and login to CSC.

Solution:
Overview
The Juniper Networks I2J Tool is a software configuration translator that converts Cisco IOS to Juniper Networks JUNOS Software full IOS Configuration files for Cisco 65xx, 75xx and 12xxx platforms into Juniper Networks JUNOS format). The tool functions via an AES 256-bit encrypted web site and supports interfaces, routing protocols, routing policy, packet filters, and Ethernet switching features. The tool dramatically reduces the time to convert software configurations, but does require the customer to review the output.

The new release of I2J adds support for our EX Series Ethernet Switches and enhances the common JUNOS routing platforms feature-set. Please refer to IOS to JUNOS Translator Release Notes for a complete list of features and commands supported by the tool.

Features
The I2J tool currently converts a great majority of IOS configuration files to JUNOS, and the Juniper Networks I2J team is increasing the conversion percentage. See the table below for currently supported and features.

The IOS to JUNOS Translator (I2J) converts full Cisco IOS configuration files for Cisco 65xx, 75xx and 12xxx platforms into Juniper Networks JUNOS format. However, not all IOS commands are translated. Hand reviewing the output is necessary. Although most IOS commands can be input singularly, this is not recommended or supported.
