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

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)

Interface: Serial0/2/0

In-bound Policy: acl 2000

Fragments matched normally

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
