[c-nsp] software advice for sup720 on Cisoc 6500 and 7600

[Arne Larsen / Region Nordjylland]

Hi all.

Can someone give me an advice about what software to use.
We are current using TDP and would like to migrate to LDP in our MPLS network.
Which release off software does support enabling off both at the same time. 
I've tried 5 or 6 different that supports both, but can't enable both at the same time.
We have some different types off Sup720.: WS-SUP720-3BXL, RSP720-3C-GE, WS-SUP720-3CXL, WS-SUP720-3C
