如图所示的网络中,交换机SWA为二层交换机,路由器RTA为各PC的网关在路由器RTA上做了如下配置:
[RTA]interface Ethernet 0/0
[RTA-Ethernet0/0]ip address 10.10.10.1 255.255.255.0 [RTA-Ethernet0/0]interface ethernet 0/0.2
[RTA-Ethernet0/0.2]ip address 20.20.20.1 255.255.255.0 [RTA-Ethernet0/0.2]vlan-type dotlq vid 2
[RTA-Ethernet0/0.2]interface ethernet 0/0.3
[RTA-Ethernet0/0.3]ip address 30.30.30.1 255.255.255.0 [RTA-Ethernet0/0.3]vlan-type dotlq vid 3
在交换机SWA上完成相应配置后,PCA、PCB和PCC都可以ping通自己的网关,下面交换机SWA端口
Ethernetl/0/4的配置应为(选择一项或多项)

A interfaceEthernet 1/0/4 port link-mode bridge port link-type trunk
Port trunk permit vlan all

B interfaceEthernet1/0/4 port link-mode bridge port link-type trunk
Port trunk permit vlan all port trunk pvid vlan 2

C interface Ethernet1/0/4 port link-mode bridge port link-type trunk
Port trunk permit vlan all port trunk pvid vlan 3

D interface Ethernet 1/0/4 port link-mode bridge port link-type trunk
Port trunk permit vlan all port trunk pvid vlan 10
