Why isn't MPLS Ping working?

I have created a static MPLS-TP connection that is passing traffic. The ingress node config is below. OSPF is used to distribute the loopback addresses.

gmpls tp-tunnel create static-ingress-corout STATIC-NODES_1_2 dest-ip 2.2.2.2 next-hop-ip 12.12.12.9 forward-out-label 666 reverse-in-label 666

mpls l2-vpn create static-vc PW-NODES-1_2 pw-id 666 peer 2.2.2.2 in-label 6666 out-label 6666 tp-tunnel-ingr-corout STATIC-NODES_1_2

 

MPLS Ping never receives a response:

3932-ONE> mpls ping tp-tunnel-ingress-corout STATIC-NODES_1_2
MPLS Ping with count (5) ttl (255) timeout (1000 ms) size (126 bytes) encap (ip/udp) reply-mode (lsp)
Legend:'!' - Success, 'X' - Error
X Seq: 1 Request Timed Out
X Seq: 2 Request Timed Out
X Seq: 3 Request Timed Out
X Seq: 4 Request Timed Out
X Seq: 5 Request Timed Out

--------------- Statistics ---------------
5 packets transmitted, 0 packets received

 

Interestingly, though, an MPLS ping on the VC does work:

3932-ONE> mpls ping vc PW-NODES-1_2                         
MPLS Ping with count (5) timeout (1000 ms) size (138 bytes) encap (ip/udp) reply-mode (lsp) fec-type (fec-128)
Legend:'!' - Success, 'X' - Error
! Seq: 1 Latency: 4 ms
! Seq: 2 Latency: 9 ms
! Seq: 3 Latency: 8 ms
! Seq: 4 Latency: 5 ms
! Seq: 5 Latency: 5 ms

--------------- Statistics ---------------
5 packets transmitted, 5 packets received
round-trip (ms) min/avg/max = 4/6/9

 

What could I be doing wrong?
