拓扑图如下:
说明:一个单臂路由实验,用2691模拟SW,版本是Software (C2691-ADVSECURITYK9-M), Version 12.4(11)T2;Clound为本机VM里装的XP,PC 2和cloud处在VLAN 10,PC1和PC3在VLAN20;补充一句,PC都是用VPCS虚拟的。
实验结果: PC1:PING VM虚拟机XP和PC 2 OK,但ping不通同一VLAN 的PC3 PC2:ping Vm虚拟机XP和PC1 OK,但ping不通PC3 PC3:连ping自身网关都ping不通 cloud:除了PC3 ping不通之外
配置: SW: ! no aaa new-model memory-size iomem 5 no ip routing no ip cef ! interface FastEthernet1/0 switchport access vlan 20 ! interface FastEthernet1/1 switchport mode trunk duplex full speed 100 ! interface FastEthernet1/2 switchportaccess vlan 10 ! interface FastEthernet1/3 switchport access vlan 10 ! interface FastEthernet1/4 switchport access vlan 20 !
Router: interface FastEthernet0/0 noip address speed 100 full-duplex ! interface FastEthernet0/0.10 encapsulation dot1Q 10 ipaddress 192.168.0.1 255.255.255.0 ! interface FastEthernet0/0.20 encapsulation dot1Q 20 ipaddress 192.168.1.1 255.255.255.0 !
疑问:这个是属于软件bug吗?还是我哪里配错了?PC3连自己的网关都ping不通,真是见鬼了。请王sir和大家指教。 |
