Which statement about BGP table and IP routing table is true?

• A. The BGP table is separate from the IP routing table in the router.
• B. The BGP table is the same as the IP routing table.
• C. BGP does not influence forwarding decisions.
• D. The IP routing table is derived entirely from BGP updates.

Answer: (A)

BGP keeps its own separate set of routes from the router’s actual forwarding table. The BGP table (often called the BGP RIB) stores every route learned through BGP with its path attributes, while the IP routing table (the forwarding table) contains the best routes from all sources that the router uses to forward packets. BGP runs its decision process to pick the best path for each prefix, and only that best path is installed into the IP routing table. Other BGP paths remain in the BGP table but are not used for forwarding unless they become the best path. Additionally, the IP routing table can be populated by routes from other sources as well, such as static routes or IGPs like OSPF.
