拓扑图

要求：

1. PC3不允许访问其他PC和Server1
2. PC2允许访问Server1服务器，不允许其他PC访问
3. 各设备IP配置如图所示，这里不做展示

AR1接口vlan配置

vlan batch 10 20 30
#
interface Vlanif10ip address 192.168.1.254 255.255.255.0 
#
interface Vlanif20ip address 192.168.2.254 255.255.255.0 
#
interface Vlanif30ip address 192.168.3.254 255.255.255.0 
#
interface Ethernet0/0/0port link-type accessport default vlan 30
#
interface Ethernet0/0/1port link-type accessport default vlan 10
#
interface Ethernet0/0/2port link-type accessport default vlan 20
#
interface GigabitEthernet0/0/0ip address 10.0.0.1 255.255.255.0
#
ip route-static 0.0.0.0 0.0.0.0 10.0.0.2

AR2接口配置

interface Vlanif1ip address 172.16.1.254 255.255.255.0
#
interface GigabitEthernet0/0/0ip address 10.0.0.2 255.255.255.0
#
ip route-static 0.0.0.0 0.0.0.0 10.0.0.1

下面开始配置基本ALC
AR1配置ACL：PC3不允许访问其他PC和Server1

[AR1]acl 2000	# 配置ACL2000
[AR1-acl-basic-2000]rule deny source 172.16.1.0 0.0.0.255	# 设置拒绝源IP地址流量
[AR1-acl-basic-2000]quit
[AR1]interface GigabitEthernet 0/0/0	# 进入接口试图
[AR1-GigabitEthernet0/0/0]traffic-filter inbound acl 2000	# 把acl2000策略应用到该接口上，检测入站流量进行匹配安全策略
[AR1-GigabitEthernet0/0/0]quit

AR1配置ACL：PC2允许访问Server1服务器，不允许其他PC访问

[AR1]acl 2010
[AR1-acl-basic-2010]rule permit source 192.168.2.0 0.0.0.255	# 设置允许该网段的流量通过
[AR1-acl-basic-2010]rule deny		# 拒绝所有流量（虽然是拒绝所有，但是会优先匹配上面一条规则）
[AR1-acl-basic-2010]quit
[AR1]interface Vlanif 30	# 进入vlan30视图
[AR1-Vlanif30]traffic-filter outbound acl 2010		# 将acl2010应用到vlan30接口上
[AR1-Vlanif30]quit

至此路由器ACL策略配置完成，下面测试PC1与Server1互通，PC2与与Server2互通
