The device will then pickup the LSP in the MPLS-TE-STD-MIB table (.1.3.6.1.2.1.10.166.3). In a snmpwalk of a device, you can check the existence of these LSPs by searching ".1.3.6.1.2.1.10.166.3.2.2.1.5" for the name of the missing LSP.
If the MIB does not contain the LSP information, then the LSP is built through the CLI command.
If the information is in neither, then no LSP will be built.
