在路由器R2上采用命令(32)得到如下所示结果。

R2>
…
R 192.168.0.0/24[120/1] via 202.117.112.1, 00:00:11, Seria12/0
C 192.168.1.0/24 is directly connected, FastEthernet0/0
202.117.112.0/30 is subnetted,1 subnets
C 202.117.112.0 is directly connected, Seria12/0
R2>
则PC1可能的lP地址为(33)，路由器R1的S0口的IP地址为(34)，路由器R1和R2之间采用的路由协议为(35)。
