第三步:设置NAT地址池
Router(Config)>Ip Nat Pool Isp1_pool 218.18.18.2 218.18.18.6 Netmask 255.255.255.224
Router(Config)>Ip Nat Pool Isp2_pool 68.18.18.4 68.18.18.10 Netmask 255.255.255.224
第四步:设置访问控制列表和NAT转换规则
Router(Config)>Access-list 100 permit Ip 192.168.0.0 0.0.0.255 any
Router(Config)>Ip Nat Inside Source Route-map Isp1 Pool Isp1_pool
Router(Config)>Ip Nat Inside Source Route-map Isp2 Pool Isp2_pool
第五步:设置ROUTE MAP规则
Router(Config)>Route-map Isp1 Permit 10
Router(Config-route-map)>Match Ip address 100
Router(Config-route-map)>Match Int Fa 0/1
Router(Config)>Route-map Isp2 Permit 10
Router(Config-route-map)>Match Ip address 100
Router(Config-route-map)>Match Int S1/0
