LAPB and X.25
Typical LAPB
Configuration
Example
By default, X.25 template is not applied on DLCIs.
In the all views, perform the following tasks to enable real-time monitoring of the
current status of LAPB and X.25.

I. Networking Requirement
Two routers are directly connected via serial ports with LABP protocol to transmit
IP data packets directly.
II. Networking Diagram
Figure 67 Direct connection between two routers via serial ports
III. Configuration Procedure
As shown in the diagram above, perform the following configuration tasks:
1 Configure Router A:
a Select interface
[Router]interface serial 0
b Specify IP address for this interface
[Router-Serial0]ip address 202.38.160.1 255.255.255.0
c Configure the link layer protocol of the interface to LAPB and specify its
working mode as DTE
[Router-Serial0]link-protocol lapb dte
d Configure other Lapb parameters (if the link is of good quality, and a higher
rate is required, the flow control parameter modulo can be increased to 128, k
to 127, but they must be the same for both ends in the direct connection)
