Can someone please provide light on "what is the backup-router concept" for in a chassis cluster SRX device?
As far as I understand, in a chassis cluster, the primary node takes the charge for routing engine so to access into the secondary node the backup-router command useful. By saying this, can I use one IP address to monitor both nodes? Example - The monitoring systems monitor only one IP which is configured in the backup-router, instead of node0 and node1 fxp0 ports. Is this possible? If it is possible, would all SRX models behave the same?
Also, how the routing works for backup-router IP? Because routing engine is only enabled on the primary node so traffic goes through the primary node. Is backup-router command does some magic which tells to the RE, if backup-router cmd configured, this is for secondary node management, something like that.....
Thanks.
