A synthetical experiment of multilayer Exchange

Requirements:

Beijing headquarter:

1, the core layer (Core1 and Core2) and the convergence layer (CDS-1,CDS-2,CDS-3 and Cds-4) using the OSPF routing protocol

2, the core layer Core1 and Core2 between the link bundle, convergence layer Cds-1 and Cds-2 do link between the bundle, Cds-3 and Cds-4 do link between the bundle

3, the core layer of Core1 and Core2 do HSRP, to achieve high availability of the network

4, the convergence layer of the switch as a root bridge, and configure load Balancing

5, Beijing Headquarters and Shanghai branch of the PC through DHCP server dynamically obtain IP address

6, Beijing Headquarters and Shanghai branch departments (C1VLAN20,C1 VLAN 30,C1VLAN40,VLAN1,VLAN2,VLAN3) can access each other, but prohibit access to C1 VLAN10 (finance Department)

Add: Route republishing at Core 2 and Route rollup at the appropriate point. Use default route when connecting to the Internet

Shanghai Branch

7, router and ds-1, ds-2 use RIP v2 routing protocol

8, ds-1 and ds-2 as Root bridge, and enable HSRP and do link bundle

9, Vlan1 can not access the company's Web server

IP Address Planning

VLAN3:192.168.3.0/24 (Gateway: 192.168.3.1)

Operation Idea:

The topology regionalization, the first branch, and then eat the headquarters

Branch topology is as follows

First, the company to fix the branch
