How to define access-list commands ?
wrong: Router(config-if)# access-list 1 permit 172.16.20.1 0.0.0.0
right: Router(config) # access-list 1 permit 172.16.20.1 0.0.0.0
The access list will be defined at global level, not at the interface level. It’s a small but important detail. The access group command will be defined at interface level:
Router(config) # int e0
Router(config-if) # access-group 1 out

What happens to a packet which receives the end of an access list ?
There is an implicit deny any at the end of an access list. So if the packet is not allowed, it will be dropped.
