1. A method comprising:
establishing an active connection between a first interface of a network device within an internal network and a first interface of a first cluster unit of a high-availability (HA) cluster, wherien the first interface of the first cluster unit is in an enabled state in which traffic directed thereto is able to be received, wherein the HA cluster provides the internal network with connectivity to an external network; concurrent with the active connection, establishing a backup connection between a second interface of the network device and a first interface of a second cluster unit of the HA cluster, wherein the first interface of the second cluter unit is in a disabled state in which traffic directed thereto is not able to be received; while the first cluster unit remains in an operational state and has connectivity to the external network, receiving and processing, by the first cluster unit via the active connection, all traffic originated by the network device that is to be transmitted onto the external network; upon determining the first cluster unit is in a failed state or the first cluster unit does not have connectivity to the external network, then causing all subsequent traffic originated by the network device that is to be transmitted onto the external network to be received and processed by the second cluster unit via the backup connection by putting the first interface of the second cluster unit into the enabled state and putting the first interface of the first cluster unit into the disabled state; and wherein a switch need not be logically or physically interposed between the network device and the first and second cluster units. |
