Hi guys,

I have the following configuration:
mpls tunnel add via 2.1.1.1 host-eth1 out-label 1024 
set int state mpls-tunnel0 up 
ip route add 192.168.3.0/24 via mpls-tunnel0 out-label 1023

Ping from CE to PE ,and the PE drop it.

That is the fib :
192.168.3.0/24
  unicast-ip4-chain
  [@0]: dpo-load-balance: [proto:ip4 index:34 buckets:1 uRPF:36 to:[15:1260]]
    [0] [@11]: mpls-label:[3]:[1023:255:0:eos]
        [@2]: mpls via 0.0.0.0  mpls-tunnel0: 
          stacked-on:

                  [@1]: mpls via 2.1.1.1 host-eth1: 00037ffffffe0e1a0d0050438847

The following is the trace info:
