(Note 1) In order to establish the LSP for VPN between a device operating with versions before Ver. 06-01 and a
device operating with versions thereafter including Ver. 06-01, it is necessary to use the VPN ID values in the range
from 1 to 255 even in a device operating with the versions thereafter including Ver. 06-01. If values outside the range
from 1 to 255 are used, the whole MPLS function may become non-utilizable in a device operating with versions
before Ver. 06-01.
