Short step-by-step screenshot guide for an initial configuration of NSRP of two Juniper ScreenOS firewalls, such as the SSGs. One screenshot pack for the https GUI and another one for the Network and Security Manager (NSM) since I am always searching for the positions of the commands on it. Finally, I am listing the appropriate CLI commands.
Remember that you must have two ScreenOS devices of the same hardware model and software version. Furthermore, at least a single interface on both devices should have the same virtual IP while both have different manage IPs. In that way, both devices are accessible after building the cluster.
The following commands have two HA interfaces configured (eth0/0 and eth0/1). Furthermore, two monitored interfaces were configured: eth0/8 and eth0/9.
NSRP commands on the master device:
set interface "ethernet0/0" zone "HA"
set interface "ethernet0/1" zone "HA"
set nsrp cluster id 1
set nsrp rto-mirror sync
set nsrp rto-mirror route
set nsrp rto-mirror session ageout-ack
set nsrp vsd-group id 0 priority 50
set nsrp vsd-group id 0 preempt
set nsrp encrypt password hBsm8xVGdpqusGT
set nsrp auth password cGvVjn5gYUF2yJK
set nsrp secondary-path ethernet0/8
set nsrp monitor interface ethernet0/8
set nsrp monitor interface ethernet0/9
