UC Start Kit 2 – 会议系统 2.1 网络结构图 2.2 用户需求 1) Cisco2811 路由器的G0/0 做外网接口IP 为/29，G0/1 做内网接口 IP/24 2) 内网 网段通过PAT 上Internet 3) 2811 做EzVPN Server 4) 2811 做CCME 5) 2811 做语音网关（FXO 连接到PSTN 或企业现用的PBX），使IP 电话能和PSTN 电话互通 6) 远程用户使用IP Communicator 通过VPN 注册到CCME,和公司内部电话互通或PSTN 互 通，节省通信费用。 7) 使用MPE 和CME 集成，远程员工和总部员工可以开voice/web 会议 2.3 配置步骤 2.3.1 清空2811 出厂设置 使用console 线连接设备console 口进行配置 缺省用户名/密码:cisco Username: cisco Password: cisco % Password expiration warning. Cisco Router and Security Device Manager (SDM) is installed on this device and it provides the default username cisco for one-time use. If you have already used the username cisco to login to the router and your IOS image supports the one-time user option, then this username has already expired. You will not be able to login to the router with this username after you exit this session. It is strongly suggested that you create a new username with a privilege level of 15 using the following command. username myuser privilege 15 secret 0 mypassword Replace myuser and mypassword with the username and password you want to use. yourname#erase startup-config //删除nvram 中的启动配置文件 Erasing the nvram filesystem will remove all configuration files!
