If the LB indication bit of an LB cell is equal to 1 and an LB location ID of the LB cell is equal to
the network element ID (LB location ID match) the loopback indication flag is set to 0 and the LB
cell is looped back (loopback point, see
cell is forwarded to the terminating segment point. This cell is looped back at the terminating
segment point (see
ID mismatch occurs the LB cell is forwarded to the terminating segment point (see
marker ú )
