Router R1 is a route reflector with clients R2, R5 and R6. Prefixes advertised by router R5 have a local preference of
200. Router R3 advertises the prefix 192.168.1.0/27 to routers R5 and R6. Assuming that none of the routers in AS
65540 is configured with "advertise-external", what is the expected output of "show router bgp routes" on router R5?
