4. Link to Path Aggregation
4. Link to Path Aggregation
This section describes how link-state information can be aggregated into path information for distribution to consumers.
Key Concepts:
- Link aggregation mechanisms
- Path-level abstraction
- ASBR to ASBR aggregation
- Multi-AS path scenarios
Sub-sections:
- 4.1. Example: No Link Aggregation
- 4.2. Example: ASBR to ASBR Path Aggregation
- 4.3. Example: Multi-AS Path Aggregation
Technical Overview: BGP-LS allows for topology abstraction where individual links can be aggregated into paths, enabling scalable distribution of network topology information across administrative domains.
