策略路由之雙出口配置實例（2）
作者：佚名
策略路由大體上分為兩種：一種是根據路由的目的地址來進行的策略稱為：目的地址路由；另一種是根據路由源地址來進行策略實施的稱為：源地址路由；隨著策略路由的發展現在有了第三種路由方式：智能均衡的策略方式。

策略路由雙出口配置調試
- R2#sh ip policy //顯示應用的策略
- Interface Route map
- Fa0/0 isp-acc
- R2#sh route-map isp-test //顯示配置的路由映射圖
- route-map isp-test, permit, sequence 10
- Match clauses:
- ip address (access-lists): 101
- Set clauses: feedom.net
- ip default next-hop 123.0.0.3
- Policy routing matches: 0 packets, 0 bytes
- route-map isp-test, permit, sequence 20
- Match clauses:
- bitscn.com
- ip address (access-lists): 102
- Set clauses:
- ip default next-hop 223.0.0.3
- Policy routing matches: 0 packets, 0 bytes
- route-map isp-test, permit, sequence 30 feedom.net
- Match clauses:
- Set clauses:
- default interface Null0
- Policy routing matches: 0 packets, 0 bytes

策略路由雙出口配置總結
策略路由雙出口配置實驗就為大家介紹完了，通過以上實驗，可以看到子網一（192.168.1.0/24）的流量都經過R2-R3的上一條鏈路選擇了ISP1鏈路，子網二（192.168.2.0/24）的流量都經過R2-R3的下一條鏈路選擇了ISP2鏈路。所以通過策略路由實現基于源的供應商選擇和網絡的負載均衡。
