Description (partial)

Symptom:
Symptoms:

    Stale LSPVIF adjacency exists on routers, in the output of the following 
command:
  <CmdBold> show adjacency <noCmdBold> 

This state is observed during the un-configuration of the routers using an
automated script. This stale adjacency does not get removed, even when
the VRF/MDT/CEF/MPLS configurations are removed. And due to this stale
adjacency, no PIM neighborship can be established, across the mLDP core
network. 
Conditions:
Conditions:
    You can possibly see this issue, if you have an automated way to delete
and add the mLDP/LSM configuration on the routers
