Wan protocol switching and routing settings

Compared with the LAN, that is, the WAN, We will summarize the WAN settings today, including the WAN protocol settings for routing and the WAN protocol for layer-3 switches. We hope that the content of this article will help you understand this aspect.

Wan protocol routing configuration

Procedure:

Enter the global configuration status config term

Enter port configuration Status interface serial slot/position

Set the HDLC Frame Type encapsulation hdlc

Set IP addresses and Their subnet masks

Ip address ip-address netmask

If the current port is connected to the DCE cable, set the clock clockrate clock-rate

Example of Wan protocol routing configuration

Vroa A has the IP address 132.4.2.2 and B has the IP address 132.4.2.1.

Configure vroa A as follows:

 
 

  
  
router# config term  
  
  
router(config)# interface serial2/0  
  
  
router(config-if)# encapsulation hdlcrouter(config-if)# ip address 132.4.2.2 255.255.0.0  
  
  
router(config-if)# clockrate 64000 
 
 

Configure vrob B as follows:

 
 

  
  
router# config term  
  
  
router(config-if)# encapsulation hdlc  
  
  
router(config-if)# ip address 132.4.2.1 255.255.0.0  
  
  
router(config-if)# clockrate 64000  
 
 

Configuration of layer-3 switches for Wan Protocol

Compared with traditional vrouters using microprocessors, L3 router switches are faster because they use ASIC-specific integrated circuits) hardware. Layer-3 multi-protocol switch (default) supports a wide range of operating systems, including layer-3 static IP routing, RIP, r00002, VRRP, and OSPFv2 routing protocols. According to the manufacturer of the product, there are different levels of advanced performance upgrades. These upgraded products allow you to take advantage of an additional set of routing protocols such as IPX, Appletalk, DVMRP, PIM-DM/SM, RSVP and other dedicated protocols, including IPv6, BGP4, and OSI, as well as load balancing and firewall functions.

Wan Protocol

Once again, according to the manufacturer's situation, there will be a network service module that configures various port interface cards. This module will provide WAN connections for E1, T1, pri isdn, bri isdn, asynchronous and synchronous communication, frame relay, X.25, and other lines. Some modules can even provide a layer-3 IP routing protocol, such as RIP, r00002, VRRP, and OSPFv2. These routing functions not only provide the device with the function of acting as a management layer-3 switch, but also provide the function of acting as a fully designated router with Wan interfaces and capabilities.

Can layer-3 switches be used in the WAN protocol?

The answer to this question depends on the actual situation and the vendor's situation. Generally, layer-3 switches have fewer functions than WAN routers. Before using a layer-3 Switch in a WAN application, you must check the following:

Does your layer-3 Switch have the physical interfaces you need, such as CSU/DSU integrated with T1 line configuration?

Can your L3 switch provide the global software functions you need?

Some examples include Frame Relay and MPLS support, VoIP packet segmentation and crossover, header compression, and firewall functions. These most important functions depend on your individual situation. In general, most people prefer to buy a fully functional WAN router instead of a layer-3 switch. In this way, they do not have to worry about being troubled by the absence of key functions.
