Hi Guys,
Appreciate if somebody can explain to me on the following. I don't quite understand the command lines below:
Router1#show ip access-lists
extended ip access list 100
10 permit tcp 172.16.16.0 0.0.0.15 host 172.16.48.63 eq 22
20 permit tcp 172.16.16.0 0.0.0.15 eq telnet host 171.16.48.63
//What does this command do? The wildcard mask 0.0.0.15 for this case means 172.16.16.15? The first line I am still alright. However, the 2nd line, I got struck.//
and
Router1(config)#int fa0/0
Router1(config-if)#ip access-group 100 in
//what does the ip access-group 100 in do?//
Pls help. Thanks.
