3,拓扑图：
4,三层交换机route-map配置,基础配置已经做好了，这里就不列出来了。
conf t
ip route 0.0.0.0 0.0.0.0 192.168.222.2
ip route 0.0.0.0 0.0.0.0 192.168.223.2
ip access-list extended line1
permit ip 192.168.90.0 0.0.0.255 any
permit ip 192.168.92.0 0.0.0.255 any
permit ip 192.168.93.0 0.0.0.255 any
ip access-list extended line2
permit ip 192.168.94.0 0.0.0.255 any
permit ip 192.168.95.0 0.0.0.255 any
permit ip 192.168.96.0 0.0.0.255 any
exit
route-map mymap permit 10
match ip address line1
set ip next-hop 192.168.222.2
exit
route-map mymap permit 20
match ip address line2
set ip next-hop 192.168.223.2
exit
sdm prefer routing
reload sdm prefer routing这条命令必须重启后才能生效
conf t
interface vlan 90
ip policy route-map mymap
ip route-cache policy
exit
interface vlan 91
ip policy route-map mymap
ip route-cache policy
exit
interface vlan 92
ip policy route-map mymap
ip route-cache policy
exit
interface vlan 93
ip policy route-map mymap
ip route-cache policy
exit
interface vlan 94
ip policy route-map mymap
ip route-cache policy
exit
interface vlan 95
ip policy route-map mymap
ip route-cache policy
exit
interface vlan 96
ip policy route-map mymap
ip route-cache policy
exit
ip local policy route-map mymap
可以查看配置：
Show route-map mymap
Show ip policy
