Reasonably configure the Alpha Routing Protocol

The rational configuration of the Alpha routing protocol network has penetrated into our daily lives. How to ensure the stability and transmission speed of the network is the top priority. This requires a good router, in the process of configuring a router, we should pay attention to removing some protocols that are useless to the LAN, so as to reduce the burden on the router and greatly enhance the network security, next we will describe the Alpha router in detail. Reasonable configuration of the routing protocol at www.2cto.com is very important for the use of router resources. We can use the passive-interface command to better control the bandwidth. To correctly configure the routing protocol, passive-interface commands are not unknown. Of course, the premise is that you must know certain knowledge about OSPF, OSPF, or RIP. 1. The passive-interface command only works in the router configuration mode. When you see the command line prompt shown below, you will know that you have entered this mode: you can use the passive-interface command to tell the dynamic routing protocol not to send network broadcasts through this interface. This command can take effect for all IP routing protocols, except for BGP. 2. This command works on OSPF, which IS a little different from IS-IS. OSPF is used, and the network interface passively specified is used as stub. It does not send or receive any route updates. When RIP, IGRP, or VPN is used, it does not send any route, but it can receive them. Similarly, it sends broadcasts to all non-passive interfaces on the network. 3. There are two ways to use the passive-interface command. Specify an interface as the passive mode, which means it will not send route updates. First, set all interfaces as the passive mode, and then on the interfaces you want to send route updates, use the no passive-interface command. Www.2cto.com 4. to change an interface to passive mode, you only need to specify the interface. Remember that this means that the system connects to the serial interface of another router, the two networks you set will be broadcast. In addition, this does not prevent your router from receiving route updates from the local network interface. If another vro is also on the LAN and sends updates to your vro, it can still receive these updates. 5. To set all interfaces as passive and open an interface separately, you only need to use the passive-interface default and no passive-interface commands to connect them through a T1 loop, all routers run RIP. each vro connects to a LAN and the computer connects to the LAN through the ethernet card. You need each vro to know the network of the other vro, right? This is why dynamic routing is used. However, on the LAN, no other routers can exchange route updates between the two routers. 6. In this case, it is a waste of LAN bandwidth and computer CPU time. If it is just a small update, it does not cause any problems, how can we eliminate such unnecessary communication? On each vro, enter the RIP configuration mode and run the passive-interface command to stop sending route updates on the LAN port. This means that the system broadcasts the two networks you set by connecting to the serial interface of another vro, this does not prevent your router from receiving route updates from the local network interface. If the other router is also on the LAN and sends updates to your router, it can still receive these updates.
