The value of vRtrMplsTpLsrFPNextHopAddrType, along with
vRtrMplsTpLsrFPNextHopAddress, specifies the forward path (FP)
IP address used as the next hop for the MPLS-TP LSP Path.
This object can be set only after vRtrMplsTpLsrFPEnabled is set to
'true'.
Once this object is set, the value may not be unset. To remove the
next hop, one must set vRtrMplsTpLsrFPEnabled to 'false'.
This object is only applicable if the vRtrMplsTpLsrFPOutLink
references a numbered interface.
