[c-nsp] ASR sending LDP Label request for unsolicited sessions

[Jorge Rabadan]

Hi all,

I am trying to setup a pseudowire between an ASR and an IXIA tester but the PW would not come up.
OSPF and RSVP are running well, the targeted LDP session is up, however the PW stays down. 
Here is the weird thing that I see on a whireshark trace:
- I can see the TLDP session properly negotiated and downstream unsolicited mode agreed between the ASR and IXIA.
- However for some reason the ASR sends an LDP Label Request to the IXIA, which is absolutely wrong for an unsolicited LDP session.
- The IXIA complains with an error notification and the PW stays down.

Has anyone come across anything similar? any suggestions?

Version is 4.3.1. Show command below.
Thank you.
Jorge
