Abstract
A first network device may establish connectivity with a second network device. The first network device may determine information that identifies a cluster identifier based on establishing connectivity with the second network device. The first network device may compare a first software version of the first network device and a second software version of the second network device. The first network device may selectively obtain and install a system image of the second network device based on comparing the first software version and the second software version. The first network device may receive, from the second network device, configuration information and user session information based on selectively obtaining the system image. The first network device and the second network device may form a high-availability cluster.
