单臂路由配置+DHCP中继+OSPF实施

需求：将R1和R2分别分入vlan10 和vlan20， 并且两个vlan内的主机都使用DHCP动态地f分别从1.1.1.0和1.1.2.0网段获得IP地址，由R4作为DHCP服务器实现DHCP中继，并保留1.1.1.250-254和1.1.2.250-254

实施-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

R1：

R1<config># int e0/0

R1<config-if># ip address dhcp

R1<config-if># no shutdown

R2:

R2<config># int e0/0

R2<config-if># ip address dhcp

R2<config-if># no shutdown

SW1:

SW1<config># vlan 10,20

SW1<config># int e0/0

SW1<config-if># switchport mode access

SW1<config-if># switchport access vlan 10

SW1<config># int e0/1

SW1<config-if># switchport mode access

SW1<config-if># switchport access vlan 20

SW1<config-if># exit

SW1<config># int e0/2

SW1<config-if># switchport trunk encapsulation dot1q

SW1<config-if># switchport mode trunk

SW1<config-if># switchport trunk allowed vlan 10,20

R3:

R3<config># int e0/0

R3<config-if># no shutdown

R3<config-if># int e0/0.10

R3<config-subif># no shutdown

R3<config-subif># ip address 1.1.1.254 255.255.255.0

R3<config-router># router-id 0.0.0.1

R3<config-router># network 1.1.1.0 255.255.255.0

R3<config-router># network 1.1.2.0 255.255.255.0

R4:

R4<config># int e0/0

R4<config-if># ip address 192.168.1.1 255.255.255.0

R4<config-if># no shutdown

R4<config-if># exit

R4<config># ip dhcp excluded-address 1.1.1.250 1.1.1.254

R4<config># ip dhcp excluded-address 1.1.2.250 1.1.2.254

R4<config># ip dhcp pool vlan10

R4<dhcp-config># network 1.1.1.0 255.255.255.0

R4<dhcp-config># default-router 1.1.1.254 (255.255.255.0)

R4<dhcp-config># dns-server 114.114.114.114 8.8.8.8

R4<dhcp-config># domain-name wuguan.com

R4<config># ip dhcp pool vlan20

R4<dhcp-config># network 1.1.2.0 255.255.255.0

R4<dhcp-config># default-router 1.1.2.254 (255.255.255.0)

R4<dhcp-config># dns-server 114.114.114.114 8.8.8.8

R4<dhcp-config># domain-name wuguan.com

R4<dhcp-config># exit

R4<config># router ospf 100

R4<config-router># router-id 0.0.0.2

R4<config-router># network 192.168.1.1 255.255.255.0
