There will be 3 entries in mplsTunnelTable. Each entry has different
mplsTuunnelInstance.

The mplsTunnelInstance "Uniquely identifies an instance of a tunnel. It is
useful to identify multiple instances of tunnels for the purposes of backup
and parallel tunnels."
You may want to put your LSPID into this field.

There will be 3 corresponding entries in mplsXCTable. Each entry has
different mplsXCLspId (RSVP-TE or CR-LDP).
