7.8.1 Example for configuring LAPB
Networking requirements
You connect two routers through serial interfaces with the LAPB protocol encapsulated to
transmit IP datagrams directly.

Router A
Router B
Configuration roadmap
The configuration roadmap is as follows:
1.
On Router A, configure the link layer protocol of the interface as LAPB and specify its
operating mode as DTE; configure other LAPB parameters such as window size and
module.
2.
Configure the link layer protocol of the interface as LAPB and specify its operating
mode as DCE; configure other LAPB parameters such as window size and module.
Data preparation
To complete the configuration, you need the following data:
•
The IP address of ready interface on Router A: 202.38.160.1/24; module: 128 and
window size: 127.
•
The IP address of ready interface on Router B: 202.38.160.2/24; module: 128 window
size: 127.
Configuration procedure
Step 1 Configure Router A.
# Configure the interface.
[RouterA] interface serial1/0/0
[RouterA-Serial1/0/0] ip address 202.38.160.1 255.255.255.0
# Configure the link layer protocol of the interface as LAPB and specify its operating mode as
DTE.
