    摘要: In one example embodiment, the method includes receiving an X.25 packet at a LAN interface of a network device. Further, the method includes determining whether a local CUG value is associated with the X.25 packet. The local CUG value may be replaced with a network CUG value associated with the X.25 packet. Thereafter, the X.25 packet, and the associated network CUG value, may be formatted to generate an IP packet. The formatting may include the use of at least one formatting regime including encapsulating the X.25 packet, that includes the associated network CUG value, in an XOT, or using protocol translation to translate the X.25 packet that includes the network CUG value into an equivalent IP packet. The method includes transmitting the IP packet using a WAN interface card, the WAN interface card including a primary interface, and at least one backup interface.
