BGP LS support

BGP-LS Support

This page has been superseded by the comprehensive BGP-LS documentation.

Current Documentation

Please refer to the current BGP-LS documentation:

Address Families / BGP-LS / Overview

What is BGP-LS?

BGP Link-State (BGP-LS) is a BGP address family (AFI/SAFI 16388/71) that distributes network topology information. It enables:

• Network topology collection for SDN controllers
• Traffic engineering path computation
• Network visualization and monitoring
• Integration with PCE (Path Computation Element) systems

Migration Note

This page exists for historical compatibility. All BGP-LS documentation has been consolidated into the Address Families section for better organization and discoverability.

Updated Documentation Includes

The new BGP-LS documentation includes:

• Comprehensive Overview: Architecture, use cases, and capabilities
• Configuration Examples: Neighbor setup and NLRI types
• API Integration: Text and JSON API examples
• SDN Integration: OpenDaylight, ONOS, proprietary controller examples
• Troubleshooting: Common issues and debugging techniques
• Production Deployment: Best practices and monitoring

RFC Reference

BGP-LS is defined in:

• RFC 7752: North-Bound Distribution of Link-State and Traffic Engineering (TE) Information Using BGP

See also:

• RFC Support - All implemented RFCs
• RFC Information - Detailed RFC implementation list

ExaBGP and BGP-LS

Important: ExaBGP does NOT manipulate the routing table (RIB) or forwarding table (FIB). It is a pure BGP protocol implementation that:

• Receives BGP-LS topology information from routers
• Sends BGP-LS updates to SDN controllers or peers
• Passes topology data to external programs via the API

Your external application (SDN controller, monitoring system, etc.) must handle the topology processing and decision-making.

Historical Context

This page was previously used for BGP-LS reference. The documentation has been reorganized to provide:

• Better organization under Address Families
• More comprehensive examples
• Integration with use case documentation
• Improved navigation and cross-references
