[RTA-rip-1]inp

[RTA-rip-1]imp

[RTA-rip-1]import-route sa

[RTA-rip-1]import-route st

[RTA-rip-1]import-route static ?

cost Metric for imported route

route-policy Apply the specified routing policy to filter routes

tag Specify route tag

<cr>

[RTA-rip-1]import-route static cost ?

[RTA]ip prefix-list abc index 10 permit 10.1.0.0 24

[RTA]rou

[RTA]route-

[RTA]route-policy abc per

[RTA]route-policy abc permit node 10

[RTA-route-policy-abc-10]if-match ip address prefix-list abc

[RTA-rip-1]import-route static route-policy abc

制造路由环路，在rta上将静态路由10.1.0.0 24的优先级修改为120

[RTA]ip rou

[RTA]ip route-static 10.1.0.0 24 10.0.1.2 pre

[RTA]ip route-static 10.1.0.0 24 10.0.1.2 preference 120

Route has been modified.
