每次打开软件路由条目缺失

lojh

我用cisco packet tracer 做了一个拓扑图，并且配置成功，然而每次关闭后再重新打开，其中一个路由器的路由条目总是部分缺失？其它的同类型路由器不会，这是为什么配置后该路由表：
Gateway of last resort is not set

     101.0.0.0/24 is subnetted, 1 subnets
C       101.0.0.0 is directly connected, Serial1/0
     102.0.0.0/24 is subnetted, 1 subnets
R       102.0.0.0 [120/1] via 101.0.0.2, 00:00:03, Serial1/0
     172.16.0.0/24 is subnetted, 4 subnets
C       172.16.1.0 is directly connected, FastEthernet0/0
C       172.16.2.0 is directly connected, FastEthernet0/1
R       172.16.3.0 [120/1] via 101.0.0.2, 00:00:08, Serial1/0
R       172.16.4.0 [120/1] via 101.0.0.2, 00:00:08, Serial1/0
     192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks
R       192.168.1.0/26 [120/1] via 172.16.1.2, 00:00:22, FastEthernet0/0
R       192.168.1.64/27 [120/1] via 172.16.2.2, 00:00:10, FastEthernet0/1
     192.168.3.0/24 is variably subnetted, 2 subnets, 2 masks
R       192.168.3.0/25 [120/1] via 101.0.0.2, 00:00:08, Serial1/0
R       192.168.3.128/26 [120/1] via 101.0.0.2, 00:00:08, Serial1/0




重新打开拓扑图后该路由表：
