E-Lab 11.2.1b - Standard ACL
Configure a standard access list for the local router Rome.
The access-list will filter traffic from the external host at 198.77.116.7.
Rome does not want this host to access either of its Ethernet LANs.
Step 1
Activate privileged EXEC mode.
Step 2
Enter global configuration mode.
Step 3.1
Using the host keyword, create a standard access-list 1 that denies traffic from the host at address 198.77.116.7.
Step 3.2
To allow traffic from hosts other than 198.77.116.7, add a second line to access list 1 that permits all IP traffic.
Step 4
Now enter interface configuration mode for Serial 0/0 to apply the access-list.
Step 5
Apply access-list 1 to the serial interface such that filtering occurs on inbound traffic.
Step 6
Type end to exit the configuration session.
Step 7
Type show access-lists to view the access-list that was created.
Step 8
View the ip interface information for Serial 0/0 to verify that the list is being applied.
