GNS3模拟器中使用rip协议，度量值有误

拓扑图如下


查看路由表发现：

/*查看R1的路由表*/

02	R1#show ip route

03

04	1.0.0.0/24 is subnetted, 1 subnets

05	C       1.1.1.0 is directly connected, Loopback0

06	R    2.0.0.0/8 [120/1] via 12.1.1.2, 00:00:11, Serial0/0

07	R    3.0.0.0/8 [120/1] via 13.1.1.3, 00:00:07, FastEthernet1/0

08	R    23.0.0.0/8 [120/1] via 13.1.1.3, 00:00:07, FastEthernet1/0

09	[120/1] via 12.1.1.2, 00:00:11, Serial0/0

10	12.0.0.0/24 is subnetted, 1 subnets

11	C       12.1.1.0 is directly connected, Serial0/0

12	13.0.0.0/24 is subnetted, 1 subnets

13	C       13.1.1.0 is directly connected, FastEthernet1/0

发现rip所学到所有路由metric都为1，别的同学有这种问题吗
