This experiment simulates two provincial networks ). It is now required that the branches in each province can communicate with the headquarters. The company's business is mainly divided into office and production. High quality transmission is required. Therefore, we recommend that you run the network data traffic on two planes, one production plane and one office plane. The production plane is on the left and the Office plane is on the right. Strict control is required. Considering the large scale of the company, the network is divided into multiple autonomous systems, each province occupies one, and the headquarters has a separate one for national data collection. This is the backbone core network of the network. Each autonomous system uses BGP to transmit routes and runs OSPF in the autonomous system. (Because it is a simulator experiment, the WAN technology will not be done, here the main thing is to do BGP networking)Lab networking requirements:Shows the experiment topology. bgp as 65000 is a national backbone network, and the following two provincial networks are from left to right: Hubei and Hunan. The national backbone network runs OSPF and BGP. R1 and R2 are the same-cluster dual-RR and establish the RRC relationship with all provincial connection routers. the data center runs OSPF region 1 and publishes a summary route to Region 0 in RT1 and rt2. AS65001 is the Hubei provincial network, RT9, and RT10 are provincial network egress routers, run BGP, and publish the production, office, link, and network management routes summarized by the provincial network in Hubei province, and use EBGP to connect the national backbone network nodes RT3 and RT4 in Hubei province; RT9 and RT10 to publish OSPF default routes to the provincial network. AS65002 is the Hunan Provincial network, RT13 and RT14 are provincial network egress routers, run BGP, and publish the production, office, link, and network management routes summarized by Hunan provincial network, and use EBGP to connect the nodes RT5 and RT6 in Hunan Province. RT13 and RT14 release OSPF default routes to the provincial network. HSRP/VRRP is run on the core Switches of the data center, Hubei and Hunan provincial networks. The production service's main network is on the left (an odd number of devices ), the Office Service Gateway is on the right (an even number of devices ). The whole network uses routing policies to distribute services. The main production business path is left, and the main office business path is right. OSPF configuration specification: Configure an OSPF passive interface on any interface that does not need to form an OSPF neighbor. Set the OSPF network type of point-to-point Ethernet to point-to-point to accelerate convergence; route summary must be prepared for each region based on the IP address plan. BGP Configuration Requirements: no synchronization; no auto-summary; Use loopback0 to create an IBGP neighbor; and configure next-hop-self on the IBGP neighbor. The WAN link is 8 Mbps, the ospf cost of the Plane Link is changed to 400, and the network type is point-to-point.IP address planning:This website uses the area allocation method after business first for IP address planning. Because it is a national network, we use the 10.0.0.0/8 address segment for allocation, the business here is only the production business and office business, coupled with the interconnection link and network management, only two digits are needed. There are more than 30 provinces in China, and we allocate six places for the region, 64. 10. business 2) Regional 6 ). sub-Business bits 8 digits ). subnet-bit host-bit 650) this. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-right: 0px "title =" 3 "border =" 0 "alt =" 3 "src =" http://www.bkjia.com/uploads/allimg/131227/0243104103-2.jpg "" 645 "=" height = "484"/> 650) this. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-right: 0px "title =" 1 "border =" 0 "alt =" 1 "src =" http://www.bkjia.com/uploads/allimg/131227/0243101204-3.jpg "" 644 "=" height = "484"/> 650) this. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-right: 0px "title =" 2 "border =" 0 "alt =" 2 "src =" http://www.bkjia.com/uploads/allimg/131227/0243102056-4.jpg "" 644 "=" height = "366"/>
There is no time to write a blog post recently. Let's take a look at this case first. We will release detailed configurations in a few days!
After such a long time, I finally sorted out the configuration! Download the attachment!
