某大学城局域网的拓扑结构如图12-4所示，图中路由器R1、R2、R3均运行基于距离矢量算法的RIP路由协议，并且图中给出了路由器R1、R2、R3各端口的IP地址信息
在路由器的特权模式下执行“show ip route”命令，得到以下部分的系统输出信息。请将以下空缺(10)～(13)处的内容填写完整，以得到路由器R1的相关路由信息表。
R1# show ip route

192.168.0.0/24is subnetted,6 subnets
C192.168.65.0 is directly connected,Serial 1
R192.168.66.0 [120/1] via ______,00:00:08, Serial 1
[120/1] via 192.168.65.1,00:00:10, ______
C192.168.67.0 is directly connected,Serial 0
C192.168.100.0 is directly connected,______
R192.168.200.0 [120/1] via 192.168.65.1,00:00:12,Serial 1
R 192.168.300.0 [120/______] via 192.168.67.2,00:00:12,Serial 0
参考答案：65.1；Serial0；Ethernet0；1
解析：由图12-4得到，通过R2的S0端口到达R1的S1端口，到达IP地址为192.168.66.0的目的网络，R2的S1端口的IP地址为192.168.65.0，得到：
192.168.66.0 [120/1] via 192.168.65.0, 00:00:08,Serial 1
[120/1] via 192.168.65.1,00:00:10, Serial0
目的网络为192.168.100.0的网络与E0直接相连，得到：
192.168.100.0 is directly connected, Ethernet()
路由器R1到达目的网络为192.168.300.0的网络，只需要经过1个路由器，即权值为1，得到：192.168.300.0 [120/1] via 192.168.67.2,00:00:12,Serial 0
