The value of vRtrMplsLspBandwidth specifies the amount of
bandwidth in mega-bits per second (Mbps) to be reserved for the LSP.
A value of zero (0) indicates that no bandwidth is reserved.
When vRtrMplsLspPathBandwidth is set to -1, the value of
vRtrMplsLspBandwidth is applied to that specific LSP/path.
