21.6.4. 策略路由

案例一

acl number 3000
 rule 0 permit ip source 192.168.2.1 0
acl number 3001
 rule 0 permit ip source 192.168.6.0 0.0.0.255
#
traffic classifier 2 operator or
 if-match acl 3000
traffic classifier 1 operator and
 if-match acl 3001
#
traffic behavior 1
 redirect next-hop 192.168.40.254
#
qos policy 2
 classifier 2 behavior 1
qos policy 1
 classifier 1 behavior 1
#
interface GigabitEthernet1/0/11
 qos apply policy 1 inbound
#
interface GigabitEthernet1/0/12
 qos apply policy 2 inbound

取消策略路由

interface GigabitEthernet1/0/11
un qos apply policy inbound
#
interface GigabitEthernet1/0/12
un qos apply policy inbound

quit
un qos policy 1
un traffic behavior 1
un traffic classifier 1

un acl number 3001

这个案例是基于源的策略路由

案例二

acl number 3010
 rule 0 permit ip source any destination 192.168.0.0 0.0.255.255

acl number 3020
 rule 0 permit ip source 192.168.6.0 0.0.0.255

traffic classifier classifier1 operator or
 if-match acl 3010
traffic classifier classifier2 operator or
 if-match acl 3020

traffic behavior behavior1
 redirect next-hop 192.168.1.1

traffic behavior behavior2
 redirect next-hop 192.168.40.254

qos policy policy1
 classifier classifier1 behavior behavior1
 classifier classifier2 behavior behavior2

interface GigabitEthernet1/0/11
 qos apply policy policy1 inbound

案例二是一个基于目的的测略路由
