As shown in the figure, all routers announce the loopback interface address in OSPF, where the R2 non-return interface address is 10.0.2.2/32, and the loopback interface address declared in Area0.R3 is 10.0.3.3/32 100.1.1.0/24 outside Routing, in order to reduce the load on the R1 router, the configuration commands are as follows:

[R1] ip pprefixt permlt 100.1.1.024
[R1]ospf1
[R1-ospf-1]Filter-policy ip-prefx 1 impot

As shown in the figure, the AS100 has two paths to the AS400. By default, the best route is transmitted from the AS200. It is known that the path to the AS400 through the AS300 is better. Therefore, the following configuration is performed on the R2. After the configuration is complete, the optimal route is not changed. Which of the following operations can make the configuration take effect?
[R2] ip as-path-filter 1 permit ^400$
R2] route-policy med permit node 10
r2-route-policy] if-match as-path-filter 1
Ir2-route-policy] apply cost 20
