CISCO 3550-24 EMI 连接宽带网，如何配置

5096169

已知公网一个固定IP ，内网有三个VLAN ，内网可以使用EIGRP路由通讯。如何配置呢？是用桥接还是路由

就是用一台三层交换机连接城域网。知道一个固定IP和网关，内网有三段IP。

你可以把F0/1设置成公网IP，然后在内部划VLAN，VLAN之间用EIGRP做路由
到外网用默认路由就可以
到特权模式：
vlan database
vlan 2 name vlan2
vlan 3 name vlan3
vtp domain xxx
vtp server
到全局模式
int range f0/2 - 10
switchport access vlan 1
int range f0/11 - 20
switchport access vlan 2
int range f0/21 - 48
switchport access vlan 3
int vlan 1
ip add 192.168.0.1 255.255.255.0
no shut
int vlan 2
ip add 192.168.1.0 255.255.255.0
no shut
int vlan 3
ip add 192.168.2.0 255.255.255.0
no shut
router eigrp 100
network 192.168.0.0 255.255.255.0
netowrk 192.168.1.0 255.255.255.0
network 192.168.2.0 255.255.255.0
int f0/1
no switchport
ip add 61.*.*.202 255.255.255.248
ip route 0.0.0.0 0.0.0.0 61.*.*.201
然后还有一些密码什么的，就不这上面写了

我这样配过了，不通啊

intel

要起用nat才能访问外网

三层交换机是不能做NAT的！
