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
