Abstract:
A tunneled networking system comprising:a first tunneled node having a first set of tunneling configuration data and at least one first backup configuration element associated therewith; a second tunneled node having a second set of tunneling configuration data and at least one second backup configuration element associated therewith; and a tunneled network between the first tunneled node and the second tunneled node, wherein the first tunneled node is operable to select a selected first backup configuration element from the set of first backup configuration elements, send a change code to the second tunneled node, and begin using the selected first backup configuration element to negotiate a backup tunneled network with the second tunneled node, and the second tunneled node is operable to receive the change code and interpret the change code to select a selected second backup configuration element from the set of second backup configuration elements, and begin using the selected second backup configuration element to negotiate the backup tunneled network with the first tunneled node.
