The IP prefix for the LDP based LSP for this OAM LSP Trace Route
test.
This parameter is mutually exclusive with the LSP name parameter
(tmnxOamLspTrCtlLspName). Either the LDP IP Prefix or the LSP name
must be specified but not both.
This object was obsoleted in release 4.0 and replaced with
InetAddress objects tmnxOamLspTrCtlLdpPrefixType and
tmnxOamLspTrCtlLdpPrefix.
