FTP request packet that enters interface S0/0/0, and is destined for an FTP server

at IP address 172.16.1.5? OU 192.168.1.5?

The router matches the incoming packet to the statement that is created

byaccess-list 201 permit ip any any command and allows the packet into the

router.

The router reaches the end of ACL 101 without matching a condition and drops the

packet because there is no statement that was created by access-list 101 permit

ip any any command.

The router matches the incoming packet to the statement that was created by

the access-list 101 permit ip any 172.16.1.0 0.0.0.255 command, ignores the

remaining statements in ACL 101, and allows the packet into the router.

OOOOOOOOOOOOOOOOOUUUUUUUU

The router matches the incoming packet to the statement that was created by the

access-list 101 permit ip any 192.168.1.0 0.0.0.255 command and allows the

packet into the router.

The router matches the incoming packet to the statement that was created by

the access-list 201 deny icmp 172.16.1.0 0.0.0.255 any command, continues

comparing the packet to the remaining statements in ACL 201 to ensure that no

subsequent statements allow FTP, and then the router drops the packet.
