What happens for already advertised labels after "ldp advertise-labels"

[yjim0140]

Referring to the following LDP configuration, what happens if the label for "59.0.0.0" has been advertised? Does it have to be withdrawn in order to satisfy "deny" of prefix-filter?

---

Router(config)# ip access-list standard pfx-filter1

Router(config-std-nacl)# deny 59.0.0.0

Router(config-std-nacl)# exit

Router(config)# mpls ldp advertise-labels for pfx-filter1

Router(config)# no mpls ldp advertise-labels

Yes, it has to withdraw for prefixes denied later.
