This object reports the name of the local interface through which the next hop of this LSP route should be reached, corresponding to the same interface identified by the standard ifIndex. Administrators use it to see, in a readable form, which physical or logical interface is actually forwarding traffic for this label-switched path. For example, this showing an interface named GigabitEthernet0/1 tells the admin exactly which port this LSP's traffic egresses through toward its next hop.
