思科华为路由器如何利用route-map配置双wan口策略路由

wan1：218.85.224.100
wan2：219.85.224.200
内网 ： 192.168.201.x 和192.168.202.x走wan1
192.168.203.x走wan2
其他网段随机wan1和wan2
一、 思科路由器：
interface GigabitEthernet0/1
ip address 219.85.224.200 255.255.255.252
ip nat outside
ip policy route-map ipsdx1

interface GigabitEthernet0/2
ip address 218.85.224.100 255.255.255.252
ip nat outside
ip policy route-map ipsdx2

ip nat pool ipsdx1 219.85.224.200 219.85.224.200 netmask 255.255.255.252
ip nat pool ipsdx2 218.85.224.100 218.85.224.100 netmask 255.255.255.252
ip nat inside source list 101 interface GigabitEthernet0/1 overload
ip nat inside source list 102 interface GigabitEthernet0/2 overload
ip nat inside source list 103 interface GigabitEthernet0/2 overload

access-list 102 permit ip 192.168.201.0 0.0.0.255 any
access-list 103 permit ip 192.168.202.0 0.0.0.255 any
route-map aaa permit 5
match ip address 102 103 <
