24、的二层通路,并尽量采用链路捆绑方式提供,CE之间不开启二层通路。如果MGW、MSS、RNC、BSC内部无法提供二层通路,则在CE之间建立二层通路,并尽量采用跨单板的链路捆绑方式提供,避免VRRP心跳中断。MGW、MSS、RNC、BSC应具有必要的网关可达性检测机制。CE与BSC、MSS、MGW之间首选静态路由,可考虑运行动态路由协议。26 Nokia Siemens Networks 26/6/2012 Zhang Lijun Flexi BSC 站点连接解决方案站点连接解决方案27 Nokia Siemens Networks 26/6/2012 Zhang Lijun 设计原则设计原则In
