Hi All:

I have succeeded. This configuration can be worked. It has succedded  =
send the "ping request" packet from HostA to Host B(label 1000)=20
and receive the "ping reply" packets from HostB to HostA.  To establish =
multi LSP between LER1 and LER2 is my following test.

Thanks for your attention.
