The value of vRtrMplsTpLspPathNextHopAddrType, along with
vRtrMplsTpLspPathNextHopAddress, specifies the IP address used as the
next hop for the MPLS-TP LSP Path.
Once this object is set, to remove the next hop, one must destroy and
recreate the vRtrMplsTpLspPathEntry.
This object is only applicable if the vRtrMplsTpLspPathOutLink
references a numbered interface.
