Playing with VPLS - only tracert gives "Request time out"

[MichaelM55]

I started a small VPLS lab: 4 switches so far, LDP with dynamic LSPs and OSPF

routing works:

display ospf routing

         OSPF Process 1 with Router ID10.0.1.3
                  Routing Tables

 Routing for Network

ping works:

ping lsp ipv410.0.1.1 32
 LSP Ping FEC: IPV4 PREFIX10.0.1.1/32 : 100  data bytes, press CTRL_C to break
 Reply from10.0.1.101: bytes=100 Sequence=1 time = 3 ms

 Reply from10.0.1.101: bytes=100 Sequence=4 time = 3 ms

 But with tracert I´m getting "Request time out"

tracert lsp ipv410.0.1.1 32
 LSP Trace Route FEC: IPV4 PREFIX10.0.1.1/32 , press CTRL_C to break
  TTL   Replier            Time    Type      Downstream

  2    10.0.1.105     2 ms    Transit  10.0.1.101/[3]
  3 Request time out
  4    10.0.1.101     4 ms    Egress

The question is why?
