策略路由该怎么进行配置呢？

策略路由不知如何配置了，太无助了

什么型号的路由器

什么设备 ？

给你找个配置案例 

1、设备接口ip地址配置

线路A

interface GigabitEthernet0/0
port link-mode route
ip address 10.10.10.1 255.255.255.252
#

线路B
interface GigabitEthernet0/1
port link-mode route
ip address 20.20.20.1 255.255.255.252

2、配置线路不可达NAQ检测

//A线路不可达探测
nqa entry admin 1
type icmp-echo //icmp探测
destination ip 10.10.10.2
frequency 100 //连续两次测试开始时间的时间间隔为100毫秒
reaction 1 checked-element probe-fail threshold-type consecutive 3 action-type trigger-only //测试失败3次触发联动
source ip 10.10.10.1

nqa schedule admin 1 start-time now lifetime forever //启动ICMP测试操作


//B线路不可达探测
nqa entry test 1
type icmp-echo
destination ip 20.20.20.2
frequency 100
reaction 2 checked-element probe-fail threshold-type consecutive 3 action-type trigger-only
source ip 20.20.20.1

nqa schedule test 1 start-time now lifetime forever

//A线路track
track 1 nqa entry admin 1 reaction 1

//B线路track
track 2 nqa entry test 1 reaction 2

3、策略路由配置

//A网段业务命中
acl advanced 3001
rule 0 permit ip source x.x.x.0 0.0.0.255

//B网段业务
acl advanced 3002
rule 0 permit ip source x.x.x.0 0.0.0.255

 //A网段分流走A线路
policy-based-route PBR permit node 10
if-match acl 3001
apply next-hop 10.10.10.2 track 1 //关联track项，A线路正常的情况下一跳生效，A线路异常NQA探测失败后此下一跳失败，进行下一条策略匹配

// //B网段分流走B线路
policy-based-route PBR permit node 20
if-match acl 3002
apply next-hop 20.20.20.2 track 2 //关联track项，A线路正常的情况下一跳生效，B线路异常NQA探测失败后此下一跳失败，进行下一条策略匹配
#
policy-based-route PBR permit node 30 //此项为必配置项，当10/20均未命中时匹配此条运行通过策略，用来实现10/20失效后匹配本地路由表

4、调用策略路由

interface GigabitEthernet0/2
port link-mode route
ip policy-based-route PBR
#
interface GigabitEthernet5/0
port link-mode route
ip policy-based-route PBR

5、配置出方向静态路由

 ip route-static 0.0.0.0 0 10.10.10.2 track 1 //A线路默认出口路由关联track项，实现下一跳不可达时路由失效
ip route-static 0.0.0.0 0 20.20.20.2 track 2 //B线路默认出口路由关联track项，实现下一跳不可达时路由失效
