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