 该自动请求过程可通过`no frame-relay inverse-arp`命令关闭，但不能设计一个停止对请求进行响应的网络。经由设计，是无法关闭反向ARP应答的，因此帧中继设备总是会通过帧中继反向ARP，尝试协助其它尝试进行`Layer 3`到`Layer 2`解析的设备（The request process can be disabled with the `no frame-relay inverse-arp` command, but you can never design a network that will stop responding to requests. By design, Inverse ARP replies cannot be disabled, so the Frame Relay speaker will always attempt to assist somebody that attempts to do a `Layer 3` to `Layer 2` resolution via Frame Relay Inverse ARP）。
 
-帧中继涉及中的反向地址解析协议行为，将自动协助先前讨论过的经由重复单播方法的广播（The Inverse ARP behaviour in the Frame Relay design will automatically assist with Broadcast through the replicated Unicast approach discussed before）。在使用反向ARP时，广播支持默认就有。

 在将两台路由器经由物理接口连接到帧中继云时，就意味着从帧中继角度讲，那些特定接口就是多点的了，因为默认物理帧中继接口就是多点结构。就算两台路由器之间的连接可能看起来是点对点的，但该连接仍是帧中继的多点连接（If you connect two routers to the Frame Relay cloud using physical interfaces, this means that the specific interfaces are Multipoint from a Frame Relay perspective, because a physical Frame Relay interface by default is a Multipoint structure. Even though the connection between the two routers may appear to be Point-to-Point, it is a Frame Relay Multipoint connection）。

 另一选项将是创建子接口，并将这些创建出来的子接口声明为多点。这类接口将与物理多点接口一样运作，因此需确定要使用的解析方法，也就是反向ARP或静态映射。也可使用两种解析方法的结合，比如在连接的一端部署反向ARP，并在另一端定义静态映射（Another option would be to create subinterfaces and declaring them as Multipoint. These types of interfaces behave exactly like the physical Multipoint interfaces, so you need to decide on the resolution method to be used, either Inverse ARP or static mappings. A combination of these methods can be used, for example, by implementing Inverse ARP on one end of the connection and defining static maps on the other end）。
 
-接口类型设置与所选的三层到二层解析方法仅本地有意义。这意味着在帧中继涉及中可以有各种变化（The interface type settings and the selected Layer 3 to Layer 2 resolution method is only locally significant. This means that you can have all kinds of variations in your Frame Relay design），比如下图表42.1中所列出的这些：
