网络配置如下图所示:
其中某设备路由表信息如下:
C 192.168.1.0/24 is directly connected, FastEthernet0/0
R 192.168.3.0/24 [120/1] via 192.168.65.2, 00:00:04, Serial2/0
R 192.168.5.0/24 [120/2] via 192.168.65.2, 00:00:04, Serial2/0
C 192.168.65.0/24 is directly connected, Serial2/0
C 192.168.67.0/24 is directly connected, Serial3/0
R 192.168.69.0/24 [120/1] via 192.168.65.2, 00:00:04, Serial2/0
则该设备为( ),从该设备到PC1经历的路径为( )。路由器R2接口S2可能的IP地址为( )。
