关于IS-IS协议的L2/L1路由渗透，下列说法正确的是？（）A、VRP平台上，缺省为不渗透，可以通过命令在L1/L2路由器配置从Level-2向Level-1进行路由渗透B、在L1/L2路由器上可以通过命令配置防止由于L2的路由渗透到L1 LSP又被发回到L2 LSP中而造成的路由环路C、利用了default metric域中的高bit作为up/down bit来避免路由环路D、路由渗透可以很好地解决L1选择次优路由出区域的问题
在IS-IS动态路由协议中，定义有L1路由器和L2路由器两种类型，它们在使用IS-IS的网络中起到不同的作用，所以网络中某一个作为物理实体的路由器不能既具有L1路由器的特性，又起到L2路由器的作用。
