    Configuration Backup and Restore Overview

    The Configuration Backup and Restore chapter of the Management and Monitoring Guide for IP/MPLSView describes the backup and restore of router configuration files, and the upgrade and downgrade of software releases for the network devices.

    Before performing configuration backup and restore, you should have created a router profile for every router that you want to back up and restore as described in Setting Up Device Profiles Overview, and then scheduled a Scheduling Live Network Collection task, as described in Live Network Collection Overview, including the collection of the configuration file and Equipment CLI.

    The default communication mechanism for configuration management is to login to the router and then run ftp, tftp, or scp from the router to the IP/MPLSView server. (Alternatively, the user can login to the router and collect the configuration file via command line interface (CLI), although this will only work for backup and not restore.)

    Hence, the IP/MPLSView server needs to be separately enabled for the selected communication method, for example, ftp, sftp, and tftp, if it is not already enabled, for example, using the “/usr/sbin/svcadm enable ftp” command. A third party tftp server can be installed for use with the Config Management module, such as http://sourceforge.net/projects/tftp-server. Contact Juniper support for the installation package for the tftp server.

    Additionally, the necessary gateways should be set up on the IP/MPLSView server for the server to reach the routers and for the routers to reach the server. Note that in the former case, a gateway to reach the router’s loopback address is sufficient. In the latter case, however, the IP/MPLSView server also needs a gateway to reach the router’s source interface IP address, that is, the interface that the router uses to reach the server. Instead of adding a separate gateway for each source interface IP address, it may be easier in some cases to add a default gateway or to add a gateway for a subnet including all of these interface IP addresses. Refer to the Getting Started Guide for IP/MPLSView for more information on setting up gateways.

    Following is a high-level outline of configuration backup and restore and the associated, recommended procedures.

    • Open the live network (File > Open Live Network) and run the Scheduling Live Network Collection task to set up Configuration file /OS management. Then open the Config/OS Management Window from the Configuration > Config/OS Manager menu.
    • To back up configuration files, select the routers to backup and click “Backup.” To restore routers to a previous collected configuration file version, modify the router entries to indicate which version to restore to. Then select the routers to restore to this configuration file version and click “Restore.”
    • To upgrade or downgrade routers, first add a software release into the software repository. Then modify the router(s) to indicate which software release each router is to be upgraded to. Select the router(s) to upgrade and click the “Upgrade” button. Users can configure whether or not to reboot automatically as part of the upgrade, or separately.
