1、某大型网络的配置实例（的确不错）说明: 这是一个比较综合的实例，从拓扑图上可以看出，它所包含的设备和技术。以下对这个例子作些说明希望能够和各位网友交流。 1.对于内部局域网，选用 Cisco 的 Catalyst 6506 作为中心交换机，二级交换采用 Catalyst 3500，同时为了说明 Trunk，又加了一个 Catalyst 2900 作为三级交换，对于终端连接用了 Catalyst 1900 交换机，这样就可以在 Catalyst 6506与 Catalyst 3500 之间以及 Catalyst 3500 与 Catalyst 2900 之间建立 Trunk，实现跨交换机的 VL
2、AN。 注：Catalyst 2900 系列如果要实现 Trunk，软件必须是企业版的，关于类似疑问可以至疑难杂谈栏目。 2.对于外连上,主要是专线连接和拨号访问,当然种类比较多.包括了 DDN、 ISDN、 Frame Relay、 E1 线路等。 3.本例给出设备的基本配置。 4.对于多设备的连接问题,值得注意的是路由问题,本实例外连部分采用静态路由而内部局域网采用动态路由. 5.在本例的帧中继配置中,运用了 IP Unnumbered ,可以节省地址资源, 有兴趣可以注意一下 在网关有关操作说明讲行很多，但很少有实例，这个配置例我想对于许多入门的朋友启发不少，我也希望这么的帖子与大家共享
3、和交流一下！配置实例 VLAN 划分问题: 对于交换设备本例中划到 VLAN 1 中, 而对于外连设备的所有以太网端口,均划到VLAN 2 中,下面给出各 VLAN 的名称和网关地址,本例划分 8 个 VLAN. VLAN ID VLAN Name Gateway VLAN 1 Bluestudy 1 10.1.0.1/16 VLAN 2 Bluestudy 2 10.2.0.1/16 VLAN 3 Bluestudy 3 10.3.0.1/16 VLAN 4 Bluestudy 4 10.4.0.1/16 VLAN 5 Bluestudy 5 10.5.0.1/16 VLAN 6 Blues
