Virtual Router
The master and backup device form a single 'virtual router'. In the following example, master
device A and backup device B form a virtual router.
Figure 55 Virtual Router
Cluster ID
You can have multiple device virtual routers on your network. Use a different cluster ID to identify
each virtual router. In the following example, devices A and B form a virtual router that uses cluster
ID 1. devices C and D form a virtual router that uses cluster ID 2.
Figure 56 Cluster IDs for Multiple Virtual Routers
Monitored Interfaces in Active-Passive Mode Device HA
You can select which interfaces device HA monitors. If a monitored interface on the device loses its
connection, device HA has the backup device take over.
Enable monitoring for the same interfaces on the master and backup devices. Each monitored
interface must have a static IP address and be connected to the same subnet as the corresponding
interface on the backup or master device.
