AS 65540 routers are iBGP fully-meshed. Prefixes advertised by router R2 have a local preference of 200. Router R1 advertises the prefix 192.168.1.0/27 to routers R2 and R3. Assuming that router R3 is configured with "advertise-external", what is the expected output of "show router bgp routes" when executed on router R4?
