Hi Jose,

If you are doing lsping to juniper box, please do check following :
1. Configure in loop back.
2. Check it's listening on udp port 3505.

"show system connections | grep 3503"
udp4       0      0  *.3503                 *.*

3. If it's a VPN scenario, please check lsping for inner LSP (by RSVP or 
  LDP) before trying for VPN lsp (by BGP).

If you need generic debugging tips for VPN, following pointer will help you.
