配置EIGRP EIGRP 支持: 快速收敛 减少带宽的使用 多个网络层协议 * Purpose: The figure introduces the IGRP routing protocol. IGRP is a sophisticated distance vector routing protocol. Emphasize: The Interior Gateway Routing Protocol (IGRP) is a dynamic distance-vector routing protocol designed by Cisco in the mid-1980s for routing in an autonomous system that contains large, arbitrarily complex networks with diverse bandwidth and delay characteristics. Historically, IGRP became one of the success factors for the early Cisco IOS software capabilities because of its superiority to RIP version 1. The important IGRP characteristics are as follows: More scalability than RIP Fast response to network changes Sophisticated metric Multiple-path support
