[j-nsp] LDP host address prefix

[Mahadesha H.S]

Hi
   Iam using juniper M5 and JUNOS version is 5.5
  whenever i advertise host address prefix to juniper, juniper send back
a notification message saying that
  bad Tlv..
   My question is
     whether juniper supports host address prefix FEC's for ldp labels
bindings..
     if it supports do i need to do any configuration for that.. it will
be helpful for me to know that as earliest as possible

thanks in advance
Mahadesha
