基于OSPF的企业内网安全优化

1.拓扑

2.IP地址规划

设备/地址/vlan****设备/地址汇聚交换机/VLAN10192.200.10.0/24汇聚交换机/VLAN20192.200.20.0/24汇聚交换机/VLAN30192.200.30.0/24汇聚交换机/VLAN40192.200.40.0/24汇聚交换机/VLAN50192.200.50.0/24汇聚交换机/VLAN60192.200.60.0/24防火墙/VLAN70/服务器网段192.200.70.0/24防火墙/VLAN80/服务器网段192.200.80.0/24

3.使用协议说明

VLAN-----------------隔离广播域,优化内网用户上网体验

SVI-------------Vlan间三层通信

DHCP---------------内网主机 自动获取IP地址

OSPF------------------提供内网路由的学习

MSTP--------------------多实例生成树,打破二层环路的同时,实现多vlan的负载均衡

VRRP------------------起到网关冗余作用

NAT--------------------地址转换,提供用户访问互联网

防火墙安全策略----------------------------提供安全策略的访问控制,以及高级的防病毒、入侵检测功能

链路聚合----------------提供链路带宽

4.设备选型

序号设备名称品牌规格单位及性能及指标产地型号数量1接入交换机华为CloudEngine S5731-H24P4XC30S5731-H24P4XC(24个10/100/1000BASE-T以太网端口,4个万兆SFP+,单子卡槽位,PoE+,不含电源)2汇聚交换机华为CloudEngine S6730-H24X6C2S6730-H24X6C(24个万兆SFP+,6个40GE QSFP28,可选license升级到6个100GE QSFP28,不含电源3核心路由器华为AR2204-24GE4AR2204-24GE(3GE WAN(1GE Combo),24 GE,1 USB,4 SIC,60W AC Power)4防火墙华为Secospace USG6310S3USG6310S-W交流主机(8GE电,1GB内存),WIFI 2.4G+5G
