The static route configuration is clear to everyone. If you do not know Baidu, you can enter the destination address and mask, you can enter the IP address of the next hop router direct connection interface or enter the outbound interface of the

Cisco product naming Rules 1. all products starting with CISCO are routers; 2. the engines starting with RSP are CISCO7500 series products; 3. all products starting with VIP are the multi-function interface processor modules of CISCO 7500 series

II. Introduction to default and static routes Note:This is a small experiment I used to study at school. I will share it with you.If you have any questions in the following command explanation and experiment, you can @ yourself. This is my contact

Router selection protocol for the advanced mode of the Network GatewayThe most fundamental starting point of routing for routing services:We need the hierarchical logical management of networks. Therefore, we need an IPv4 Network to allow

The differences between network devices such as switches, routers, hubs, and NICs and the network adapter and the router are two network hardware devices. The NIC is the interface device between the network terminal and the network, and the router

[Network layer] router Composition 1. Concept routing refers to the activity difference in moving information from the source location to the target location through a interconnected network: the main difference between routing and switching? The

OSPF route selection and troubleshooting case description this case involves the LSA selection problem in specific circumstances of OSPF. This problem is related to the FA address and some NSSA features. By analyzing faults one by one, we also

PING is the most commonly used troubleshooting command. It consists of a group of ICMP response request packets. If the network runs normally, a group of response packets will be returned. ICMP messages are transmitted using IP data packets.

Next, the router is divided into the following router: (the premise is that the master route has been successfully connected to the network) is only the approximate step: the master route, the next Route 1. the secondary route is disconnected from

Wireless route connection 1. the master route is configured as normal and configured to be able to access the Internet normally. 2. first, change the LAN interface to the network parameter-> LAN port settings, change the IP address of the LAN port,

Configuring SSH services on a Cisco router currently Cisco products only support SSH-1, not SSH-2. The following uses GSR 12008 as an example to describe the configuration method of the SSH-1 (configuration input command in italic): ① configure

Basic knowledge-determine the number of routers from the local machine to another machine how to determine the number of routers from the local machine to another machine: You can use the TTL In the ping command to determine, the default TTL is

An Analysis of the transmission of an IP packet through a router transmission through a router. Each host and route has a routing table ). The route table specifies the route for the IP address of the destination to be sent. It's like a road sign.

Verify that any computer that uses TCP/IP as the network protocol has a route table. When a network packet is transmitted from a computer using TCP/IP to another computer using TCP/IP, the route is determined by the route table of the computer that
