局域网地址，外部网络不可达
至于用几层交换机，那得看你有多少节点，网络怎么样的拓扑了
简单网络，二层交换机就可以
复杂网络，就需要三层交换机
【 在 VShaka (昵称) 的大作中提到: 】
: Because you’re interested in “high performance,” you want to do everything possible to keep the cluster network from reducing performance. A common approach is to put the cluster on a private Ethernet network. The address space is unroutable, so the compute nodes will effectively be “hidden” from a routable network, allowing you to separate your cluster logically from a public network.

: 下面这段“unroutale”address space是什么意思？就是结点之间用交换机而不能用路由器？
