After learning the foundation of the PPP protocol, we have a new understanding of its concept and authentication content. Today, we will mainly explain the experiment content on configuring PPP authentication, DDR, and Multilink to gain a deeper understanding of the configuration skills of ISDN and dial-up networks.
1. Tutorial Purpose
Through this experiment, you can master the following skills:
Configure ppp chap authentication;
Configure dialer map;
Configure DDR
Configure Multilink;
View and monitor related information.
2. device requirements
The device requirements in this experiment are exactly the same as those in Experiment 1. For more information, see Experiment 1.
3. topology and Configuration
The topological structure of this experiment is 7-2. R1 and R2 routers connect one isdn bri line respectively.
To configure the DDR, create an API (L0) on R1 and R2 respectively ).
The IP addresses of BRI interfaces, L0 interfaces, and ISDN numbers of the connected routers are marked in Figure 7-2.
The experiment requires that R1 and R2 be configured to connect the network segments from 10.1.1.0/24 to 10.1.2.0/24 and provide the security of the dial-up connection, use the corresponding command to implement the 128 kbit/s connection bandwidth between R1 and R2.
4. Experiment configuration and monitoring results
The experiment uses the DDR, PPP authentication, and PPP Multilink technologies. Let's look at how to configure a router to meet the requirements of the experiment.
Configuration list 7-2 is the specific configuration of R1 and R2.
