BGP LS support
This page has been superseded by the comprehensive BGP-LS documentation.
Please refer to the current BGP-LS documentation:
Address Families / BGP-LS / Overview
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
This page exists for historical compatibility. All BGP-LS documentation has been consolidated into the Address Families section for better organization and discoverability.
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
- BGP-LS Overview - Main documentation
- Address Families Overview - All supported address families
- SDN Integration - SDN controller integration patterns
- Traffic Engineering - TE with BGP-LS
- Network Monitoring - Topology collection use cases
- Configuration Syntax - General configuration guide
- Neighbor Configuration - BGP neighbor setup
- API Overview - API architecture
- Text API Reference - Text format examples
- JSON API Reference - JSON format examples
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
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.
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
- Segment Routing - SR-MPLS and SRv6
- Traffic Engineering - TE strategies
- EVPN Overview - EVPN for data centers
