As a port device connecting WAN, vrouters have been widely used. Their main function is to connect multiple independent networks or subnets to achieve optimal routing and datagram transmission between the Internet. This article takes the Cisco 2511 vro as an example to introduce four router configuration methods. 1. Use the Cisco router master port OSOLE to conne
confidence of a routing protocol. The lower the ad value, the higher its priority. For routing information between two different routing protocols to a destination, the router first determines which protocol to trust based on the administrative distance.

There are many things worth learning about the configuration mode of a Cisco router. Here we mainly introduce the mode of user execution and privilege of a Cisco router. 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 m

An instance of VLAN configuration for Cisco L3 switches and L2 SwitchesCisco VLAN implementation is usually port-centric. The port connected to the node determines the VLAN in which it resides. There are two ways to allocate a port to a VLAN: Static and Dynamic. The process of creating a static VLAN is to forcibly allocate the port to a VLAN. That is, we first create a VLAN on The VTP (VLAN Trunking Protoco
