标准ACL 实验人：高承旺

实验名称：标准acl

实验要求：

不让1.1.1.1 ping通3.3.3.3

实验拓扑：

实验步骤：

网络之间开启RIP协议！

[R1]rip

[R1-rip-1]ver 2

[R1-rip-1]undo summary

[R1-rip-1]net 192.168.1.0

[R1-rip-1]net 1.0.0.0

[R1-rip-1]q

[R2]rip

[R2-rip-1]ver 2

[R2-rip-1]undo summary

[R3-rip-1]net 192.168.2.0

[R3-rip-1]net 3.0.0.0

[R3-rip-1]q

通3.3.3.3

配置好动态路由后，测试能R1ping

配置ACL访问控制列表

[R2]firewall enable

[R2]firewall default permit

[R2]acl number ?

INTEGER<2000-2999> Specify a basic acl

INTEGER<3000-3999> Specify an advanced acl

INTEGER<4000-4999> Specify an ethernet frame header acl

INTEGER<5000-5999> Specify an acl about user-defined frame or packet head [R2]acl number 2000

[R2-acl-basic-2000]rule ?

INTEGER<0-65534> ID of acl rule

deny Specify matched packet deny

permit Specify matched packet permit

[R2-acl-basic-2000]rule deny source 1.1.1.1 ?

0 Wildcard bits : 0.0.0.0 ( a host )

X.X.X.X Wildcard of source

[R2-acl-basic-2000]rule deny source 1.1.1.1 0

[R2]int s0/2/0

[R2-Serial0/2/0]firewall packet-filter 2000 ?

inbound Apply the acl to filter in-bound packets

outbound Apply the acl to filter out-bound packets

[R2-Serial0/2/0]firewall packet-filter 2000 inbound

ACL查看命令

显示配置的访问控制列表的规则

[R2]display acl all

Basic ACL 2000, named -none-, 1 rule,

ACL's step is 5

rule 0 deny source 1.1.1.1 0 (5 times matched)

[R2]display firewall-statistics all

Firewall is enable, default filtering method is 'permit'.

Interface: Serial0/2/0

In-bound Policy: acl 2000

Fragments matched normally

From 2010-12-17 11:07:09 to 2010-12-17 11:16:29

0 packets, 0 bytes, 0% permitted,

5 packets, 420 bytes, 20% denied,

20 packets, 1072 bytes, 80% permitted default,

0 packets, 0 bytes, 0% denied default,

Totally 20 packets, 1072 bytes, 80% permitted,

Totally 5 packets, 420 bytes, 20% denied.

配置完事ping不通的

[R1]ping -a 1.1.1.1 3.3.3.3

PING 3.3.3.3: 56 data bytes, press CTRL_C to break Request time out

Request time out

--- 3.3.3.3 ping statistics ---

5 packet(s) transmitted

0 packet(s) received

100.00% packet loss

在1上配置出站ACL ，把方法一在R2上的配置去掉！[R1]firewall enable

[R1-acl-basic-2000]rule 20 deny source 1.1.1.1 0

[R1-Serial0/2/0]firewall packet-filter 2000 outbound

[R1]int s0/2/0
