can any one get these lines meaning for srx240 firewall and what impact that it gives.
These commands are used to configure node specific information like: host-name, management interface configuration, etc..
On configuring these commands you can access both nodes of a cluster independently using their fxp0 IPs.
Routing daemon would run only in primary node, hence you would need backup-router configuration to reach management network.
These config is to get the management access via fxp0 of a node which is secondary for RG0 group; the back up router config is needed as routing sub-system will not be running in secondary node.
You can refer the below KB for more details
Thanks for your reply and i am still unable to get the backup-router concept and can you just explain that.
As we have given same ip and destination for the backup-router in node 0 and node 1, why is it so ?
backup-router 192.168.253.254 is the gateway to reach private management network.
And destination denotes the subnet of management network.
Backup-router IP would be in the same subnet as that of your fxp0 IP.
If fxp0 IPs of two nodes are of different subnet and connected to different switch/L3 device, then you can have different backup-router ip.
In myexperience, typical deployment would be to have single management network and fxp0s of both nodes connected to same switch(in this scenario your backup-router and destination would be the same).
Thank you all,
My doubts clarified.
