思科双核心配置实例

1. ①、PC1（192.168.10.100）和PC2（192.168.200.100），代表处于不同子网的两台客户机，IP设置为自动获取模式。Switch1和Switch2分别是子网的接入交换机。分配的管理地址为：Switch1（192.168.10.2）和Switch2（192.168.20.2）。②、网络参数由DHCP下发。如果Switch1和Switch2这两台交换机无法配置DHCP服务，就必须将DHCP服务配置在路由器Router1和Router2上，则需要分别在路由器的Ethernet0扩展槽上加装HWIC-4ESW模块。③、Router1和Router2为两台互为热备份的路由器。④、Router0和Switch0组成的子结构为验证子结构，用来模拟局域网外的验证主机或者互联网上的某个节点。假定节点的IP地址为172.16.10.99。
