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