经典的三层网络案例分析

经典的三层网络案例分析。 目的:让不同的vlan 之间可以互相通讯。 IP规划 vlna ID ip网段 vlan网关 vlan 1 172.16.1.0/24 172.16.1.7-9 vlan 2 172.16.2.0/24 172.16.2.252-254 vlan 3 172.16.3.0/24 172.16.3.252-254 vlan 4 172.16.4.0/24 172.16.4.252-254 vlan 5 172.16.5.0/24 172.16.5.252-254 vlan 6 172.16.6.0/24 172.16.6.252-254 vlan 7 172.16.7.0/24 172.16.7.252-254 vlan 8 172.16.8.0/24 172.16.8.252-254 vlan 9 172.16.9.0/24 172.16.9.252-254 拓朴图见最后面 路由器配置 一、cisco路由器配置: Enable Configure terminal Service password-encryption Hostname cisco1721 Enable secret 654321 Enable password 123456 ip subnet-zero ip name-server 202.96.134.133 202.96.172.218 interface fastethernet 0 ip address 61.142.221.5 255.255.255.240 speed auto no shutdown interface serial 0 ip unnumbered fastethernet 0 encapsulation ppp no fair-queue bandwidth 2048 no shutdown exit ip classless ip route 0.0.0.0 0.0.0.0 serial 0 no ip http server line con 0 line aux 0 line vty 0 4 password 12345678 login no scheduler allocate end copy running-config startup-config reload 请注意NAT等是在防火墙设置的. 交换机配置 一、Catalyst 4006-s3交换机配置: Enable Configure terminal service pad service password-encryption hostname c4006-s3 enable password 123456.
