Explanation

BGP Link-State (BGP-LS) distributes IGP link-state and traffic-engineering information to external applications such as a PCE. Because the topology contains two distinct IGP areas, the PCE needs BGP-LS information from a router in each area: R3 for IGP Area 1 and R4 for IGP Area 2. This provides the complete topology and TE view required for end-to-end LSP path computation.
