某中小型企业有四个部门分别是市场部、行政部、研发部和工程部请合理规划IP地址和VLAN实现企业内部能够互联互通同时要求市场部、行政部和工程部能够访问外网环境(要求使用OSPF协议)研发部不能访问外网环境(通过访问控制列表实现)。为了保证网络的可靠性配置MSTPVRRP多备份组实现负载均衡解决单点故障问题。同时在出口路由器上实现NAT地址转换使企业内部主机使用ISP提供的内部全局地址访问外网环境提高网络整体的安全性。 2、配置要求 (1)四个部门分别在不同网段、不同 VLAN实现VLAN间通信; (2) LSW1和LSW2为接入交换机LSW3和LSW4为核心交换机R1为出口路由器; (3)市场部和研发部属于MSTP实例1 VRRP主路由器为LSW3备份路由器为LSW4; (4)行政部和工程部属于MSTP实例2 VRRP主路由器为LSW4备份路由器为LSW3; (5)ISP分配给该企业的内部全局地址为1.1.1.0网段; (6)外网服务器IP地址为200.0.0.0/24网段; (7)合理规划核心交换机和路由器之间的互联地址; (8)访问控制要求:研发部不能访问外网。 企业网络拓扑结构如图1所示: 问答来自CSDN weixin_44257060
实验拓扑 实验配置
1.创建vlan并划分相关接口
交换机之间采用trunk交换机和路由或终端设备使用access
vlan b 10 20 30 40 11(vlan11用于与路由器相接)
p l t
p t a v 10 20 30 40 11 2.配置MSTP
stp region-configuration
instance 1 vlan 10 30 instance 2 vlan 20 40
region-name HHH revision-level 1
active region-configuration
stp instance 2 root primary stp instance 1 root secondary 3.配置相关IP地址
服务器地址 4.设置vrrp组
int vlan 10
vrrp vrid 10 virtual-ip 172.16.10.254
int vlan 20
vrrp vrid 20 virtual-ip 172.16.20.254
vrrp vrid 20 priority 120
vrrp vrid 20 track interface g0/0/1 reduced 40 int vlan 30
vrrp vrid 30 virtual-ip 172.16.30.254 int vlan 40
vrrp vrid 40 virtual-ip 172.16.40.254
vrrp vrid 40 priority 120
vrrp vrid 40 track interface g0/0/1 reduced 40 5.配置ospf
交换机可ping通服务器 有邻居建立 此时pc可ping通服务器 6.ACL限制研发部访问200.0.0.0网段 rule 5 deny ip source 172.16.30.0 0.0.0.255 destination 200.0.0.0 0.0.0.255
限制研发部访问接口下调用研发部无法访问200.0.0.0网段 全局配置
