Replacing the Routing Engine: File Transfer Method
To replace and configure a Routing Engine by transferring files from another node in a chassis cluster (node
0 is used as an example):
1. Ensure that the firmware image is available on node 1 in the /var/tmp folder. You can download the
firmware from https://support.juniper.net/support/downloads/ .
2. Save a local copy of the configuration in the /var/tmp folder on node 1:
user@node1# show configuration | save /var/tmp/cfg-node1
3. Prepare to shut down node 0:
a. Perform a manual failover of the redundancy groups (RGs) from node 0 to node 1.
Fail over RG1:
root@node0> request chassis cluster failover redundancy-group 1 node 1
Fail over RG0:
root@node0> request chassis cluster failover redundancy-group 0 node 1
b. Verify that both RGs are active on node 1 after the failover:
root@node0> show chassis cluster status
{secondary:node0}
root@node0> show chassis cluster status
