GMPLS interface update - 3: added MPLS interface ADMIN-STATUS handler

Added #MPLS-interface #ADMIN-STATUS #handler routine in GMPLS module. This enables to #perform the #support #procedure s for #MPLS-interface s on ADMIN-STATUS change. The handler is register ed with the IF module and #IF #module will #execute this #call-back #on respective #parameter #change in IF module. This helps to perform the necessary procedures in GMPLS module when the ADMIN-STATUS is changed from IF module.

GMPLS interface update - 1: added MPLS interface create/remove sequence

Added #MPLS-interface #create / #remove #sequence in GMPLS module. This enables to #create #MPLS-interface s #through the #IF #module #interface #management operations. On creating the MPLS logical-interface in the IF module the corresponding interface is created in the GMPLS module through the logical-interface handler routine. On removing the MPLS logical-interface in IF module, corresponding operations are performed in GMPLS module accordingly. The #MPLS-interface #activation and #ADMIN-STATUS operations are performed in the GMPLS module #through the appropriate logical-interface #handler #routine s defined by GMPLS module for the same, and the triggers for these operations are passed from the IF module to GMPLS module through these handlers.

IF update - 13: updating logical interface status handler

Updated the #logical-interface #hierarchical #status #handling routines in IF module. The #status #change #handler routines has been #upgraded for the new data-structure changes. The hierarchical status handler #propagate s the interface #status #from the #lower interface #layer s #to the #higher #layer s. The interface #stacking enables the interface status to be decided based on the lower layer component interfaces. The interface status will depend on it's own #ADMIN-STATUS, #interface-type dependent #procedure s and #lower layer #interface #OPER-STATUS.

IF update - 10: updating extended logical interface entries

Updated the #extended #create / #remove routines for #logical #interface framework in IF module. The #agent level #traversal #routines and #mapper routines has been #upgraded for the new data-structure changes. The #interface #admin-status #handler has been adapted for the new changes.
