A router is running BGP and receives more than one route for a particular prefix. Assume all the routes for this prefix have the same attributes. Which three path features would be reasons be for the rou ter to ignore some of the routes and not consider them as candidates for the best path?（）

• A、paths from an internal BGP (iBGP) neighbor if the local autonomous system (AS) appears in the AS_PATH
• B、paths for which the NEXT_HOP is inaccess ible
• C、paths from an external BGP (eBGP) neighbor if the local autonomous system (AS) appears in the AS_PATH
• D、paths for which the NEXT_HOP is accessible
• E、paths that are marked as synchronized in the show ip bgp output
• F、paths that are marked as  not synchronized in the show ip bgp output
