Description: This table contains objects for mapping previously defined entries in mplsFTNTable to interfaces.

This table provides the capability to activate or map FTN entries defined in mplsFTNTable to specific interfaces in the system. FTN entries are compared with incoming packets in the order in which they are applied on an interface. For this reason, this table provides a mechanism to 'insert' an FTN entry between two existing FTN entries already applied on an interface.

Using this linked-list structure, one can retrieve FTN entries in the order of application on a per-interface basis as follows:

- To determine the first FTN entry on an interface with index ifIndex perform a GETNEXT retrieval operation on mplsFTNMapIndex.ifIndex.0.0; the returned object, if one exists, is (say) mplsFTNMapIndex.ifIndex.0.n. Then the index of the first FTN entry applied on this interface is n.

- To determine the FTN entry applied after the one indexed by n perform a GETNEXT retrieval operation on mplsFTNMapIndex.ifIndex.n.0; the returned object, if one exists, is (say) mplsFTNMapIndex.ifIndex.n.m. Then the index of the next FTN entry applied on this interface is m.

Use the above steps to retrieve all the applied FTN entries on a per-interface basis in application order. Note that the number of retrieval operations is the same as the number of applied FTN entries (i.e. the minimum number of GETNEXT operations needed using any indexing scheme).
