The above information shows that a TCP connection is established
normally between LSRs. If a TCP connection is not established
normally, the information is shown as below.

Local binding means local label distribution and notifying to other
LSRs. Remote binding means that the label is notified by LSP
peer. For local network segment, when a LSR receives the label
imp-null, the LSR implements penultimate hop popping mecha-
nism.
