You are troubleshooting a BGP routing issue between your network and a customer router and are reviewing the BGP routing policies. Which two statements are correct in this scenario? (Choose two.)
A.
Export policies are applied to routes in the RIB-ln table.
B.
Import policies are applied to routes in the RIB-Local table.
C.
Import policies are applied after the RIB-ln table.
D.
Export policies are applied after the RIB-Local table.
In BGP, routing policies are used to control the flow of routing information between BGP peers1.
Option C suggests that import policies are applied after the RIB-In table. This is correct because import policies in BGP are applied to routes that are received from a BGP peer, before they are installed in the local BGP Routing Information Base (RIB-In)1. The RIB-In is a database that stores all the routes that are received from all peers1.
Option D suggests that export policies are applied after the RIB-Local table. This is correct because export policies in BGP are applied to routes that are being advertised to a BGP peer, after they have been selected from the local BGP Routing Information Base (RIB-Local)1. The RIB-Local is a database that stores all the routes that the local router is using1.
Therefore, options C and D are correct.
