(The dual-machine of juniper firewall has high redundancy and security, and is easy to manage. It is divided into three networking modes: A/P networking mode of layer3, full-mesh A/P networking mode of layer3, full -A/A networking mode of mesh. Among them, the layer3A/P mode has the lowest environmental requirements and is a widely popular configuration in the industry. However, its utilization rate is not high, and only one firewall manages network traffic at the same time, providing redundant switching when one side link and device fail. The configuration requests that the hardware and software versions are the same, the interface numbers are the same, and the interfaces put into the HA must be the same.
