Cisco router configuration manual Virtual LAN (VLAN) routing 1. The main network technology we currently use when constructing an enterprise network is generally based on exchange and virtual networks. The exchange technology changes shared media to exclusive media, greatly improving the network speed. The Virtual Network Technology breaks the restrictions of the geographical environment. without changing t

Cisco L3 switch Policy Routing for network access and Traffic DistributionI. Description of the solution environment 1. There are two groups of Group1 and Group2 in the environment, respectively, to access the Internet from two different network outlets. 2. The core network is a Cisco 3560G layer-3 Switch with four VLANs. VLAN10/VLAN20 belongs to Group1 and VLAN3

Hot Backup Routing protocol Hsrp:cisco Private protocolEnsures that when the network edge device or access link fails, the user communication can be quickly and transparently restored to provide redundancy for the IP network, by using the consent virtual IP address and virtual MAC address, two or more routers on the LAN segment can be used as a virtual router for external services.HSRP enables Cisco routers

[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 that VLAN10 and VLAN20 members can obtain IP a

A comprehensive case of Cisco inter-VLAN routing and HSRP topology Description: www.2cto.com 1. R3 and R4 simulate the customer's pc, which belong to vlan10 and vlan20 respectively. Vlan10 and vlan20 represent different departments in reality. 2. SW1 is a layer-3 switch, and SW2 is a layer-2 switch. 3. R5 simulates the internet. R5 has a lo0: 5.5.5.5/24 loop port.

Basic knowledge of Cisco Routing Router The simplest network can be imagined as a single-line bus. Each computer can send packets to the bus to communicate with each other. However, as the number of computers in the network increases, this is not feasible and will cause many problems: 1. bandwidth resources are exhausted.2. Each computer wastes a lot of time processing unrelated broadcast data.3. The netwo

Layer controls the traffic on the Logical Link. This logical connection may span a series of data links.Application Layer, Session Layer, and presentation layer:The application layer corresponds to the OSI application layer, Session Layer, and presentation layer. Some routing selection protocols use this layer. For example, Border Gateway Protocol (BGP) and Route Selection Information Protocol (RIP ). However, the most common service in the applicati
