Hi Tom, Thnak you for your reply. I agree that your method can get a 2nd label during a local repair in use. However, before using a local repair, I do not understand why your method can get a 2nd label. A Cross-Connect in the MPLS-LSR-STD-MIB for the 2nd label is only created during the local repair in use. So, before using a local repair, I think I can not get the 2nd label. Is this correct?
