華為策略路由配置實(shí)例

1、華為策略路由配置實(shí)例公司20.1 30.1/24圖1策略路由組網(wǎng)示例圖如上圖1所示，公司用戶通過Switch雙歸屬到外部網(wǎng)絡(luò)設(shè)備。其中，一條是低速鏈路，網(wǎng)關(guān)為10.1.20.1/24 :另外一條是高速鏈路，網(wǎng)關(guān)為10. 1. 30. 1/24公司希望上送外部網(wǎng)絡(luò)的報(bào)文中，IP優(yōu)先級(jí)為4、5、6、7的報(bào)文通過高速 鏈路傳 輸，而IP優(yōu)先級(jí)為0、1、2、3的報(bào)文則通過低速鏈路傳輸。2、配置思路1、創(chuàng)建VLAN并配置各接口，實(shí)現(xiàn)公司和外部網(wǎng)絡(luò)設(shè)備互連。2、配置ACL規(guī)則，分別匹配IP優(yōu)先級(jí)4、5、6、7,以及IP優(yōu)先級(jí)0、1、2、3、3、配置流分類，匹配規(guī)則為上述ACL規(guī)則，使設(shè)備可以對(duì)報(bào)文進(jìn)行區(qū)分
