*1 It is necessary to increase the memory of all RPs installed in the device.
*2 It is necessary to increase memory so that the minimum required memory is provided only for the relevant RPs
(the memory required for each RP differs).
*3 Min. band guarantee with kbit/s designated is a QoS queue attribute of configuration definition data in WAN (6Mbit/
s or less, excluding ISDN) and is a mode that is designated by the bandwidth_kbps parameter.
*4 Remote-gateway path entry required for MPLS operation is included in the path entry count.
