The output shows that Router A and Router C have received FEC-label mappings only from Router B.
Router B has received FEC-label mappings from both Router A and Router C. Router D does not
receive FEC-label mappings from Router A or Router C. LDP has established an IPv6 LSP only over
the link Router A—Router B—Router C.
