The LSRs compare their LDP Identifiers as unsigned integers. The LSR with the larger LDP Identifier may assign only odd-numbered VCIs in the VPI/VCI range as labels.

However, there could not be a third entry with LowerBound vpi/vci == 0/200 and UpperBound vpi/vci == 0/300 because this label range overlaps with the second entry (i.e., both entries now have 0/200). A row will not become active unless a unique and non-overlapping range is specified. At least one label range entry for a specific LDP Entity MUST include the default VPI/VCI values denoted in the LDP Entity Table.
