routing between subnets cisco

The concept, installation, configuration, and use of GNS3 are described earlier, and this article describes how to use the GNS3 configuration IOU to enable routing Exchange experiments using GNS3 and Cisco IOU.Since this is a long story, I'll go through the outline first:1. Introduction to IOU Simulation environment2. Preparation of IOU Software environment3. Installation, import, and configuration of VMwar

protocol between as is called the External Gateway Protocol External Gateway Protocol (also called Inter-Domain routing protocol): there are two types of inter-domain routing protocols: externalGateway Protocol (EGP) and Border Gateway Protocol (BGP)2) Dynamic routing according to the algorithm can be divided into: Distance vector

Routers are packet forwarding devices that work in the third layer of the OSI Reference Model-the network layer. Routers implement network interconnection by forwarding packets. Although routers can support a variety of protocols (such as TCP/IP, ipx/spx, AppleTalk, etc.), most routers in China run TCP/IP protocol. Routers typically connect two or more logical ports identified by an IP subnet or Point-to-Point protocol, with at least one physical port. The router determines the output port and t

Problem description You can define your own rules to route data packets, not just the destination address. Here You can learn how to use policy-based routing to solve this problem. In specific applications, policy-based routes include: ☆Source IP address-Based Policy Routing ☆Policy Routing Based on data packet size ☆Application-Based Policy

Cisco single-ARM routing configurationOne-arm routing, which is to set up multiple logical subinterfaces on the router, one VLAN for each sub-interface. The data on each sub-interface is passed on the physical link to be labeled encapsulated. Cisco devices support ISL and 802.1q (dot1q) protocols. Huawei only supports

only bridging/switching in A large network. Logically, the solution is to divide a large network into several small networks, but this is impossible in a class-based address system. To solve this problem, a new domain: subnet mask appears. The subnet mask specifies the network address and host address. In the subnet mask, binary 1 indicates the network address bit, and binary 0 indicates the host address bit. The subnet mask of traditional IP addresses is: Class A: 255.0.0.0 Class B: 255.255.0.

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

How to build a routing Exchange experiment using GNS3 and Cisco IOU-Installation ChapterGNS3installation of softwareWe recommend that you download the latest version of GNS3 directly from the official website, the official website is connected http://www.gns3.com/Select the appropriate version according to the system type, here I choose the latest version of the WINDWOS system 1.3.2650) this.width=650; "hei

[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

In order to allow Cisco switched remote connections to the security of the account password improved, you can use SSH to connect the terminal, but many factory switches default iOS is not supported by the SSH feature, in order to enable Cisco switches to support SSH, must upgrade with "K9" iOS. The following is the factory Cisco 3750g-24ts default iOS screenshot
