Configuring Label Advertisement Control (Outbound Filtering)
Perform this task to configure label advertisement (outbound filtering).
By default, a label switched router (LSR) advertises all incoming label prefixes to each neighboring router.
You can control the exchange of label binding information using the mpls ldp label advertise command.
Using the optional keywords, you can advertise selective prefixes to all neighbors, advertise selective prefixes
to defined neighbors, or disable label advertisement to all peers for all prefixes.
Prefixes and peers advertised selectively are defined in the access list.
Note
Before You Begin
Before configuring label advertisement, enable LDP and configure an access list.
