This will not only allow you to connect to each device separately, but it is also a requirement for track-ip when used and for the cluster to operate properly. The procedures below are based on screenOS 6. Routing entries both static and dynamic can be synchronized as well.

First, pick junipsr interface on both devices to be used as HA link.

So on both cluster devices, put this interfaces in nsrp mode:. Next, create the cluster on the first device. The prompt now indicates that the device is master M. The arp, auth and encrypt statements are optional.

In the current setup, the device can failover when the other device goes down. This is optional and is only required if you want to do interface based failover. Keep in mind that not just the interface will failover. The entire device will failover. I usually configure the master device uuniper a priority of 50 and enable preempt:. On the backup device, the configuration is pretty much the same, except for the priority and preempt:. This will make sure that, if the master goes down e.

When the cluster devices are configured, they will start synchronizing information. You can check if the configurations are in sync by running:. Before the cluster is fully in sync, you should force sync, by running on the backup device!


After the reboot of the passive backup device, the cluster is fully operational. Even if you have create a cluster on an existing device junipper added a second new, empty device into the cluster, you only have to reboot the passive node and the active node always stays online.

These commands will force the primary master device to step down. The other device will become master right away. You can verify which one of the devices is master 14 performing the routines explained at http: Cluster members can have different hostnames. Ik kan daar erg weinig documentatie over vinden, los van de instructie hoe het in te regelen.

Heb jij daar een idee over?

These are the main requirements to set up a cluster: You need to mznual at least one free interface on each device to interconnect the device HA link. Use the same interface number on both devices.

It makes no real sense to build a cluster if your switches are not redundant as well. Just something to keep in mind. SSG5 devices require an additional license. This is the protocol used by Netscreen to set up and operate a cluster VSD: This means that they have the same configuration. A VSD can be in any of the following states: This device monitors the state of the master and takes over when the master fails Initial: Upon initial NSRP configuration, the VSD group member that has the lowest closest to zero priority number will become the master device.


But there may be a reason where you want to control the election. The backup device takes control. Suppose the master device is broken and you need to replace it and the replacement unit has a lower mac address.

So you reconfigure the new device with the same VSD information, same priority. You connect the master device back and all of a sudden both devices have an empty config.

So it pushes its empty config to the other device and the entire cluster is broken. This scenario can be avoided by setting different priorities, or by manually setting the node that has the entire config to preempt mode.

This will ensure that this node with preempt enabled will become the master even if the other node has a lower priority. The preempt holddown parameter specifies how junlper a device will wait for another device with higher priority to assume the master role before it takes over. You can control how many ARP packets are sent upon failover. You can interconnect the devices with a crosscable or with a switch between the 2 devices.

The secondary is only used for heartbeat unless the primary HA link goes down HA link protection: So on both cluster devices, put this interfaces in nsrp mode: Save local configuration successfully.
