What are the minimum NSRP commands required? For assistance with configuring a pair of firewalls for NSRP, follow the steps below.

Perform basic configuration on Firewall-A. Bind the interfaces to the zones desired, and configure an IP address on the interfaces.

Configure the NSRP cluster id: Configure NTP command, if applicable. Repeat steps 2 – screnos for Firewall-B. The basic configuration steps for the following topology are documented in this solution.


Firewall’s with identical ScreenOS versions and license keys Firewall’s with identical hardware At least one interface on each firewall to be configured in the HA zone, which will be used for carrying control channel information For more information on the software and hardware requirements for NSRP, refer to KB These instructions were performed on a SSG The same concept applies to the other models that support NSRP; the difference being the interface notation or dedicated HA port.

Then proceed to the next step when ready to configure NSRP.

For more information on assigning the HA ports, refer to KB Other NSRP firewall pairs on the same segment must have a different set of cluster ids. Once the cluster id is set to a value, all the security screenoz will become part of the VSD-group 0, by default. Each NSRP nuniper member can have different host names. Defining a single name for all cluster members allows SNMP communication and digital certificates use to be continued without interruption after failover.


To define a single name for all cluster members, type the following CLI command: Only one digital certificate is required for an NSRP cluster. Yes – Enter the command: Then continue to Step 7.
