The most prominent feature of NHRP is that it avoids extra router hops in an NBMA with multiple LISs. To this goal, NHRP provides the source with the NBMA address of the destination, if the destination is directly attached to the NBMA. If the destination station is not attached to the NBMA, then NHRP provides the source with the NBMA address of an exit router that has connectivity to the destination. In general, there may be multiple exit routers that have connectivity to the destination. If NHRP uses the services of a dynamic routing algorithm in fulfilling its function, which is necessary for robust and scalable operation, then the exit router identified by NHRP reflects the selection made by the network layer dynamic routing protocol. In general, the selection made by the routing protocol would often reflect a desirable attribute, such as identifying the exit router that induces the least number of hops in the original routed path.

NHRP最显著的特点是，它避免了具有多个LIS的NBMA中额外的路由器跳数。为此，如果目的地直接连接到NBMA，则NHRP向源提供目的地的NBMA地址。如果目标站未连接到NBMA，则NHRP向源提供连接到目标的出口路由器的NBMA地址。通常，可能有多个出口路由器连接到目的地。如果NHRP使用动态路由算法的服务来实现其功能，这是稳健和可扩展操作所必需的，那么由NHRP标识的出口路由器反映了网络层动态路由协议所做的选择。通常，路由协议所做的选择通常会反映期望的属性，例如识别在原始路由路径中引起最少跳数的出口路由器。
