Copying a Configuration File from One Routing Engine to the Other

You can use either the console port or the management Ethernet port to establish connectivity between the two Routing Engines. You can then copy or use FTP to transfer the configuration from the master to the backup, and load the file and commit it in the normal way.

To connect to the other Routing Engine using the management Ethernet port, issue the following command:



user@host> request routing-engine login (other-routing-engine
| re0 | re1)

On a TX Matrix platform, to make connections to the other Routing Engine using the management Ethernet port, issue the following command:



user@host> request routing-engine login (backup
| lcc number | master | other-routing-engine
| re0 | re1)

For more information about the request routing-engine login command, see the JUNOS System Basics and Services Command Reference.

To copy a configuration file from one Routing Engine to the other, issue the file copy command:



user@host> file copy source destination

In this case, source is the name of the configuration file. These files are stored in the directory /config. The active configuration is /config/juniper.conf, and older configurations are in /config/juniper.conf {1...9}. The destination is a file on the other Routing Engine.

The following example copies a configuration file from Routing Engine 0 to Routing Engine 1:



user@host> file copy /config/juniper.conf
re1:/var/tmp/copied-juniper.conf

The following example copies a configuration file from Routing Engine 0 to Routing Engine 1 on a TX Matrix platform:



user@host> file copy /config/juniper.conf
scc-re1:/var/tmp/copied-juniper.conf

To load the configuration file, enter the load replace command at the [edit] hierarchy level:



user@host> load replace /var/tmp/copied-juniper.conf

Caution: Make sure you change any IP addresses specified in fxp0 on Routing Engine 0 to addresses appropriate for Routing Engine 1.
