Options

• AExport policies are applied to routes in the RIB-ln table.
• BImport policies are applied to routes in the RIB-Local table.
• CImport policies are applied after the RIB-ln table.

• B

• C
  71% (46)

Explanation

In BGP, routing policies are used to control the flow of routing information between BGP peers. 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). The RIB-In is a database that stores all the routes that are received from all peers. 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). The RIB-Local is a database that stores all the routes that the local router is using.
