如何设置能让PC0能ping通service0且经过router0上网，PC1，2，3能经过router0上网，PC4，5能ping通service0 感谢万分

Answer 1

ip地址都改成192.168.0.xxx

追答

也就是是哦吧你所有的电脑都组成同一个ip段的局域网

Answer 2

假设你的PC0、PC1、PC2、PC3分别接3560的10/11/12/13口，server0接3560的2口，路由器的1口接3560的24口（路由器端地址为10.10.10.1/30，核心端地址为10.10.10.2/30），2950的1口接3560的1口，所有业务网段的网关都是 .1，
PC4接2950的4口，PC5接5口
路由器0口接公网，公网地址为100.100.100.2，掩码255.255.255.252，网关100.100.100.1，那么，设备配置如下：
2950配置:
vlan 14
vlan 15
interface fastEthernet 0/1
switchport mode trunk
interface fastEthernet 0/4
switchport access vlan 14
switchport mode access
interface fastEthernet 0/5
switchport access vlan 15
switchport mode access
3560配置：
vlan 11
vlan 12
vlan 13
vlan 14
vlan 15
vlan 100

interface FastEthernet0/1
switchport trunk encapsulation dot1q
switchport mode trunk

switchport access vlan 100
switchport mode access
interface FastEthernet0/10
switchport access vlan 10
switchport mode access
interface FastEthernet0/11
switchport access vlan 11
switchport mode access
interface FastEthernet0/12
switchport access vlan 12
switchport mode access
interface FastEthernet0/13
switchport access vlan 13
switchport mode access
interface FastEthernet0/24
