cisco support of ldp host address FECs

I am wondering how I would configure my cisco 7206 for ldp host address fecs. When my cisco gets label mapping messages with prefix fecs (fec tlv type 2 as opposed to fec tlv type 3) with a prefix length of 32, it does the right thing, The label binding is added to the ldp lib and the mpls forwarding table is updated appropriately. However, when the cisco recieves a label mapping with a host address fec, it does nothing with the message. It seems to just drop it. How do I configure the cisco to do the appropriate thing with these label mappings?? Are host address fecs supported by cisco??

Host FECs are curently supported. We use an address prefix with a /32 to accomplish the same. A notification is sent to the peer issuing this type of FEC and this event should be logged locally on the receiving router as well.

Hope this helps,
