局域网虚拟路由及双ISP局域网虚拟路由及双ISP.doc

一、配置路由器接口IP地址： R1： conf t int f0/0 ip add 172.16.1.1 255.255.255.0 no shut exit int f0/1 ip add 172.16.2.1 255.255.255.0 no shut exit int s0/0 ip add 201.0.0.1 255.255.255.0 no shut exit int s0/1 ip add 202.0.0.1 255.255.255.0 no shut exit R2: conf t int s0/0 ip add 201.0.0.2 255.255.255.0 no shut exit int s0/1 ip add 203.0.0.1 255.255.255.0 no shut exit R3: conf t int s0/0 ip add 202.0.0.2 255.255.255.0 no shut exit int s0/1 ip add 204.0.0.1 255.255.255.0 no shut exit R4: conf t int s0/0 ip add 203.0.0.2 255.255.255.0 no shut exit int s0/1 ip add 204.0.0.2 255.255.255.0 no shut exit int lo0 ip add 4.4.4.4 255.255.255.0 no shut exit 二、配置交换机接口 Sw3: en vlan database vlan 10 vlan 20 exit conf t int f0/1 sw mode access sw access vlan 10 exit int f0/2 sw mode access sw access vlan 20 exit int range f0/3 , f0/4 sw mode trunk switchport trunk encapsulation dot1q switchport trunk allowed vlan all exit end Sw1: en vlan database vlan 10 vlan 20 exit conf t int f1/14 sw mode trunk switchport trunk encapsulation dot1q switchport trunk allowed vlan all exit int f1/15 no switchport ip add 172.16.1.2 255.255.255.0 no shut exit int vlan 10 ip add 192.168.10.1 255.255.255.0 no shut exit int vlan 20 ip add 192.168.20.2 255.255.255.0 no shut exit Sw2: en vlan database vlan 10 vlan 20 exit conf t int f1/14 sw mode trunk switchport trunk encapsulation dot1q switchport trunk allowed vlan all exit int f1/15 no switchport ip add 172.16.2.2 255.255.255.0 no shut exit int vlan 10 ip add 192.168.10.2 255.255.255.0 no shut exit int vlan 20 ip add 192.168.20.1 255.255.255.0 no shut exit 三、发布内网路由 Sw1: conf t router rip ver 2 net 192.168.10.0 net 192.168.20.0 net 172.16.1.0 no auto-summary exit Sw2: conf t router rip ver 2 net 192.168.10.0 net 192.168.20.0 net 172.16.2.0 no auto-summary exit R1: conf t router rip ver 2 net 172.16.1.0 net 172.16.2.0 no auto-summary redistribute static exit ip route 0.0.0.0 0.0.0.0 s0/0 ip route 0.0.0.0 0.0.0.0 s0/1 end
