Use the undo mpls ldp label-accept command to cancel the configuration.

# Configure to deny the Label Mapping information of 1.1.1.1 through 1.1.1.3. 
First, configure the corresponding IP Prefix.

# Then, configure a specific IP Prefix that will be used in the policy for filtering 
ingress label mapping.

label-advertise: Specifies a filtering policy for label mapping advertisement

fec-ip-prefix: FEC address prefix list

By default, the labels of all destination addresses are advertised to all LDP peers.
