S3 is a VTP server with S2 as a client." The serial link between R1 and R2 is Frame Relay." The serial link between R2 and R3 uses HDLC encapsulation." The serial link between R1 and R3 is authenticated using CHAP." R2 must have secure login procedures because it is the Internet edge router." All vty lines, except those belonging to R2, allow connections only from the subnetsshown in the topology diagram, excluding the public address." Source IP address spoofing should be prevented on all links that do not connect to otherrouters." Routing protocols must be used securely
