企业项目拓扑1

某企业骨干网络拓扑如下图所示:

企业项目拓扑1

企业网络要求如下:

实验要求:
1.R1为企业内网设备,R2为ISP供应商网络;
2.企业内网运行MSTP协议保证网络可靠性和负载均衡;
3.PC1、PC2自动获取ip地址且可以互相ping通;
4.R1为企业DHCP服务器;
5.企业内网运行OSPF协议和NAT使得内外网互通;
6.允许Client1所在网络可以访问Server1的所有服务,
且只允许访问Server2的FTP服务;
7.Client2所在的网络仅允许访问server1和Server2的www服务;
8.企业网络设备可以被R2远程管理。

第一步:配置基本网络;

SW1基本配置

interface GigabitEthernet0/0/1
port link-type trunk
port trunk allow-pass vlan all
interface GigabitEthernet0/0/2
port link-type trunk
port trunk allow-pass vlan all
interface GigabitEthernet0/0/3
port link-type access
port default vlan 100
interface Vlanif10
ip address 192.168.10.254 255.255.255.0

interface Ethernet0/0/4
port link-type access
port default vlan 10
R1配置如下
sysname R1
interface g0/0/1
ip address 100.1.1.2 24
interface g0/0/0
ip address 192.168.100.1 24
interface g0/0/2
ip address 192.168.30.254 24
R2配置如下
sysname R2
interface g0/0/0
ip address 100.1.1.1 24
interface g0/0/1
ip address 200.1.1.254 24

第二步:配置STP;

STP配置
SW1配置如下:
stp region-configuration
region-name ntd
instance 10 vlan 10
instance 20 vlan 20
active region-configuration
quit
stp instance 10 priority 8192
stp instance 20 priority 8192
SW2配置如下:
stp region-configuration
region-name ntd
instance 10 vlan 10
instance 20 vlan 20
active region-configuration
quit
stp instance 10 priority 4096
SW3配置如下:
stp region-configuration
region-name ntd
instance 10 vlan 10
instance 20 vlan 20
active region-configuration
quit
stp instance 20 priority 4096

第三步:配置OSPF

SW1配置如下
ospf 1
area 0.0.0.0
network 192.168.100.0 0.0.0.255
area 0.0.0.10
network 192.168.10.0 0.0.0.255
area 0.0.0.20
network 192.168.20.0 0.0.0.255
R1配置如下
ip route-static 0.0.0.0 0.0.0.0 100.1.1.1
ospf 1
default-route-advertise always
area 0.0.0.0
network 192.168.100.0 0.0.0.255
area 0.0.0.30
network 192.168.30.0 0.0.0.255
stub no-summary

第四步:配置DHCP并进行测试;

DHCP配置
R1配置
dhcp enable
ip pool p1
gateway-list 192.168.10.254
network 192.168.10.0 mask 255.255.255.0
lease day 7 hour 0 minute 0
dns-list 8.8.8.8
ip pool p2
gateway-list 192.168.20.254
network 192.168.20.0 mask 255.255.255.0
lease day 7 hour 0 minute 0
dns-list 8.8.8.8
interface GigabitEthernet0/0/0
dhcp select global
quit
SW1配置
dhcp enable
interface Vlanif10
dhcp select relay
dhcp relay server-ip 192.168.100.1
interface Vlanif20
dhcp select relay
dhcp relay server-ip 192.168.100.1
quit
测试如下图:

    第五步:配置NAT和ACL,并进行测试;
在企业出口路由器R1进行设置
首先,设置内网acl,使得Client1仅允许访问Server2的FTP服务,Client2仅允许访问Server2的www服务,acl设置如下:

acl number 3000
rule 10 permit tcp source 192.168.10.0 0.0.0.255 destination 192.168.30.1 0 des
tination-port eq ftp
rule 15 permit tcp source 192.168.10.0 0.0.0.255 destination 192.168.30.1 0 des
tination-port eq ftp-data
rule 20 deny ip source 192.168.10.0 0.0.0.255 destination 192.168.30.1 0
rule 30 permit tcp source 192.168.20.0 0.0.0.255 destination 192.168.30.1 0 des
tination-port eq www
rule 40 deny ip source 192.168.20.0 0.0.0.255 destination 192.168.30.1 0
interface GigabitEthernet0/0/2
traffic-filter outbound acl 3000

如下图Client1可以访问Server2的FTP服务,但不可以访问WWW服务:

企业项目拓扑1
企业项目拓扑1

     如下图Client2可以访问Server2的www服务,但不可以访问FTP服务:

企业项目拓扑1
企业项目拓扑1

 其次,设置外网acl,使得Client1仅允许访问Server1的所有服务,Client2仅允许访问Server2的www服务,acl设置如下:

外网acl设置
acl number 3001
rule 10 permit tcp source 192.168.20.0 0.0.0.255 destination 200.1.1.1 0 destin
ation-port eq www
rule 20 deny ip source 192.168.20.0 0.0.0.255 destination 200.1.1.1 0
rule 30 permit ip
quit
interface GigabitEthernet0/0/1
nat outbound 3001
如下图Client2可以访问Server1的www服务,但不可以访问FTP服务,内网中其他设备并不受影响:

至此,企业内网网络配置及验证完成!!!
