Part 03. Setting DHCP

hostname R1
do writ
int e0/0
ip addr 12.1.1.1 255.255.255.0
no shut
int e0/1
ip addr 192.168.1.1 255.255.255.0
no shut
exit
ip dhcp pool DHCP
network 192.168.1.0 /24
default-router 192.168.1.1
dns-server 8.8.8.8
ip route 23.1.1.0 255.255.255.0 e0/0 12.1.1.2
ip route 192.168.2.0 255.255.255.0 e0/0 12.1.1.2
hostname R3
do writ
int e0/0
ip addr 23.1.1.3 255.255.255.0
no shut
int e0/1
ip addr 192.168.2.1 255.255.255.0
no shut
exit
ip dhcp pool DHCP2
network 192.168.2.0 /24
default-router 192.168.2.1
dns-server 8.8.8.8
ip route 192.168.1.0 255.255.255.0 e0/0 23.1.1.2
hostname R2
do writ
int e0/0
ip addr 12.1.1.2 255.255.255.0
no shut
int e0/1
ip addr 23.1.1.2 255.255.255.0
no shut
ip route 192.168.1.0 255.255.255.0 e0/0 12.1.1.1
ip route 192.168.2.0 255.255.255.0 e0/0 23.1.1.3
ip route 192.168.2.0 255.255.255.0 e0/1 23.1.1.3
ip dhcp
sh ip
ping 192.168.1.1

設定完 R3 和 R2 的 IP 後：

ping 12.1.1.1
ping 12.1.1.2

將 R2 設置 router 後重 ping 12.1.1.2：

ping 12.1.1.2
ping 23.1.1.2
ping 23.1.1.3
ping 192.168.2.1

R3 重設後：

ping 192.168.2.1

R2重設後：

ping 192.168.2.2
ip dhcp
sh ip
ping 192.168.2.1
