On many occasions, you can configure the Cisco router to become a Frame relay switch. and supports multiple routers to form a larger frame relay switch via NNI connections.
In this paper, R2 and R3 are interconnected to form a large switch to communicate R1 and R4.
R2:
for remote connection in a wide area network. In fact, frame relay technology is still a network connection technology. As long as the network administrator master the key points of its management, he can still easily face it. Specifically, you need to master the following four key points when managing frame relay.
1. Master the management and configuration of local management interfaces
The local manageme
This experiment is to configure a general router as a frame relay switch to provide a frame relay experimental environment for other experiments in this chapter.1. Tutorial PurposeThrough this experiment, you can master the following skills:● Configure a frame relay environment with only two nodes;● Configure a star fr
In the LAN working environment, encounter network virus attack is always unavoidable things, once the workstation accidentally infected with the network virus, then it can not be normal access to the Internet; In addition, users to change the IP address at will, the local area network is prone to the phenomenon of IP address conflict, once such a failure occurs, Workstations will also not be able to access the Internet properly. In order to control the Internet access stability, this article sta
Topology map:
1. Configure the router R4 as a Frame relay switch
Frame-relay switching * configured as Frame Relay switch
2. Configure the interface's clock frequency, package type, LMI type and Frame Relay DCE on the route
A frame relay switch is a useful device, either in the lab or elsewhere. Like the boot register, the setting of the frame relay switch is also very profound in the router settings. You can build many different network models by learning how to configure a frame relay
Lab environment:
1. the topology is simple, but classic. The experiment is completed using the GNS simulator.
2. Four 36XX routers, one of which is configured as FR-SW. The router is directly connected to the frame relay switch.
Lab requirements:
1. configure a vro as a frame relay switch
2. The other three routers are

We have introduced the configuration of the DHCP Server of the H3C switch. I wonder if you have a clear idea. Here, we will continue with the previous article to explain the content of the DHCP Relay configuration of the H3C switch.

Use a cisco router to simulate how to configure a frame relay switch (configure 3640 as a frame relay switch): 3640 (config) # frame-relay switching ---------------------- enable the frame relay switching function of the router 36
The core switch is still quite common. So I studied how to use the DHCP relay of the core switch to increase security performance. I would like to share it with you here and hope it will be useful to you. In a LAN environment, network virus attacks are always inevitable. Once a workstation is accidentally infected with a network virus, it cannot access the Intern
Case Description: "Light control Project" in the single-chip microcomputer through the IO port control relay, relay access to GPRS circuit board power supply, so as to achieve the single-chip microcomputer on the GPRS circuit board switch control

Required components: a five-pin relay, 1 NPN
Simply record that a Cisco router is simulated as a frame relay switch, and the router must have a serial interface module. Liehuo.net

. Turn off the power supply in case of wiring. The p9_1 is a 3.3V power supply with the p9_13 (GPIO number 31) as the control signal output: One boot you will find that the LED is on. Enter the system operation SYSFS, as follows: When you change the direction to out, the light goes out and the value is zero. Turn the value to 1 and the light will light up again. I am not satisfied with the result. Again, this time lose that troublesome transistor, switch
[Cisco] DHCP relay, layer-3 Switch VLAN Routing PracticeThe experiment topology uses the GNS3 0.8.6 simulator to build a DHCP server using Red Hat 6.5. The experiment requires configuring a layer-3 Switch VLAN routing so that VLAN10 and VLAN20 members can access each other. Performs DHCP relay for layer-3 switches so t
