MPLS Label Filtering
- By default LDP will generate & advertise labels for every prefix in the local routing table.
- To filter & generate labels only for required prefixes

- example:
- create access list:
- """access-list 10 permit 150.1.0.0 0.0.255.255"""

- """no mpls ldp advertise-labels"""
- use of access list to filter the label generation
- """mpls ldp advertise-labels for 10"""
- Before MPLS label filtering:
- After MPLS label filtering:
