Description (partial)


    Stale LSPVIF adjacency exists on routers, in the output of the following 
  <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
    You can possibly see this issue, if you have an automated way to delete
and add the mLDP/LSM configuration on the routers
