Description: Each entry indicates the application of a particular entry as defined in mplsFTNTable on an interface. The order of application of FTN entries on an interface is the order in which they will be compared against incoming packets for a match. Each entry of this table is indexed by the interface index that the FTN entry is applied to, with the value 0 representing all interfaces, the index of the previous FTN entry applied on the interface and the index of the current FTN entry. This linked-list indexing style structure allows FTN entries to be inserted at arbitrary positions in the list. Agents MUST NOT allow the same FTN entries to be applied multiple times to the same interface. Agents MUST NOT allow the creation of rows in this table until the corresponding rows are created in the mplsFTNTable. If the corresponding row in the FTN table is destroyed, the agent MUST destroy the corresponding entries in this table as well. Although it is strongly recommended that managers destroy rows in this table in such a way that keeps the remainder of the table consistent, agents MUST ultimately make sure that if an entry in this table is destroyed, that inconsistencies in the table are not allowed to occur. To this end, rows that are no longer appropriate should be taken out of service.
