The Atlanta Bread Company is again reviewing the costs incurred
by the Macon office for dialin access to the core router. The CTO
has recommended that Stacker compression be added to the
asynchronous link between Atlanta and Macon to maintain
compatibility with the Cisco 700 series. You will configure
compression between the Atlanta core router and the Macon remote
office.
Notes:
Lab Tasks:
Log into the Atlanta router and enter global configuration mode.
Configure the serial interface for stacker compression. The
command to configure the serial interface is:
Atlanta(config)#interface serial 0/1
Atlanta(config-if)#ppp compression stacker
Atlanta(config-if)#ip tcp header-compression
Below is a brief description of each of the above commands:
PPP compression stacker
The Stacker (LZS) compression algorithm will be used. Stacker is CPU
intensive.
IP tcp header-compression
Compresses only the headers of the TCP packet and disables fast
switching.
Write the configuration to memory.
Log into the Macon router and enter global configuration mode.
Configure the serial interface to perform stacker compression.
The command to configure the serial interface is:
Macon(config)#interface serial 0/1
Macon(config-if)#ppp compression stacker
Macon(config-if)#ip tcp header-compression
Write the configuration to memory.
From the Macon router issue the following command:
Macon#ping atlanta
Setup an FTP server or web server on the Atlanta fastethernet
segment and a workstation with FTP client software on the Macon
fastethernet segment and transfer both compressed and uncompressed
files. While you do this issue the following command:
Macon#show compression
Record your findings about the compression process below:
What is a negative of turning on compression?
List the other types of compression algorithms:
Congratulations! You now have squeezed every penny out of the
Atlanta to Macon dialup connection!
