All labels are advertised to all neighbors by default.

The no mpls ldp advertise-labels command without any op-

tional parameter forbids the distribution of any locally assigned
labels. To restore the distribution of all locally assigned labels, use
the mpls ldp advertise-labels command without any optional
parameter. Only standard ACL is supported now.
Up to 99 mpls ldp advertise-labels commands can be executed,
those commands work together to determine how LSR advertises
local labels. In the case that multiple commands are configured,
the following rules should be followed:
1. Each mpls ldp advertise-labels command has a (prefix acl,
peer acl) pair. The access list pair is (none, none) when no op-
tional parameter is specified; and it is (prefix-acl, none) when
the optional parameter is specified but without the keyword
no.
2. There is only one (prefix acl, peer acl) pair "applied to" each
prefix in accordance with the following rules:
i. One (prefix acl, peer acl) pair "applies to" one prefix only
ii.
3. When LSR is to advertise a prefix label, it executes the following
operations:
i. Finds the (prefix acl, peer acl) pair "applied to" the prefix.
ii.
iii. In the case that one (prefix acl, peer acl) pair "applied to"
iv. If prefix acl permits the prefix and there is no peer acl
v. If prefix acl permits the prefix and there is one peer acl, the
This command takes effect immediately after its configuration.
The command can be configured only when the network in sta-
ble status. Otherwidse, it could not take effect immediately. Do
not use this command frequently.

In the case that there is more than one (prefix acl, peer
acl) pair "matching" a prefix; the first (prefix acl, peer acl)
pair "applies to" the prefix (in the sequence configured in
show running-config).
In the case that there is no (prefix acl, peer acl) pair
