思路與配置：
1.配置SW1：創建vlan10和vlan20
將0端口加入vlan10 2和3端口加入vlan20
vlanif10 ip：192.168.10.254 255.255.255.0
vlanif20 ip：192.168.20.2 255.255.255.0
2.配置SW2：創建vlan30 40 50 60
將5端口加入vlan30 4端口加入vlan40
將1和2端口加入vlan50 1和6端口加入vlan60
vlanif30ip：192.168.30.254 255.255.255.0
vlanif40ip：192.168.40.254 255.255.255.0
vlanif530ip：192.168.50.2 255.255.255.0
vlanif60ip：192.168.60.24 255.255.255.0
3.配置R1： 配置0端口ip：192.168.20.254 255.255.255.0
配置1端口ip：192.168.12.1 255.255.255.0
配置2端口ip：192.168.100.254 255.255.255.0
4.配置R2： 配置0端口ip：192.168.50.254 255.255.255.0
配置1端口ip：192.168.12.2 255.255.255.0
配置2端口ip：192.168.60.254 255.255.255.0
5.配置SW3 創建vlan100
將1端口加入vlan100
vlanif100ip：192.168.100.1 255.255.255.0
7.配置R1 創建RIP
rip
version 2
network 192.168.12.0
network 192.168.20.0
network 192.168.100.0
8.配置SW2 創建RIP
rip
version 2
network 192.168.30.0
network 192.168.40.0
network 192.168.50.0
network 192.168.60.0
9.配置R2 創建RIP
rip
version 2
network 192.168.12.0
network 192.168.50.0
network 192.168.60.0
10.配置sw3 創建RIP
rip
version 2
network 192.168.100.0
如果手動配置pc機的ip 此就可以全網互通
11.配置SW3的地址池：系統模式下 dhcp enable
ip pool vlan10
network 192.168.10.0 mask 255.255.255.0
gateway-list 192.168.10.254
dns-list 1.1.1.1
lease day 3
VLAN 20 30 40 50 60 同上
進入vlan100端口 選擇全局模式
interface g0/0/0
dhcp select global
12.配置SW1：開啓中繼 dhcp enable
interface vlanif 10
dhcp select relay
dhcp relay sever-ip 192.168.100.1
13.配置R1：開啓中繼 dhcp enable
interface g0/0/0
dhcp select relay
dhcp relay sever-ip 192.168.100.1
14.配置SW2：開啓中繼 dhcp enable
interface vlanif 30
dhcp select relay
dhcp relay sever-ip 192.168.100.1
interface vlanif 40
dhcp select relay
dhcp relay sever-ip 192.168.100.1
15.配置R2：開啓中繼 dhcp enable
interface g0/0/0
dhcp select relay
dhcp relay sever-ip 192.168.100.1
interface g0/0/2
dhcp select relay
dhcp relay sever-ip 192.168.100.1
配置完成
