1、配置EIGRP路由协议,EIGRP协议概述,EIGRP是最典型的平衡混合路由选择协议,它融合了距离矢量和链路状态两种路由选择协议的优点,使用散射更新算法,可实现很高的路由性能。 EIGRP特点如下: 采用不定期更新,即只在路由器改变计量标准或拓扑出现变化时发送部分更新路由。 支持可变长子网掩码。 具有相同的自治系统号的EIGRP和IGRP之间,可无缝交换路由信息。 关键还有:IGRP不支持VLSM和不连续的子网。,EIGRP 支持不同的网络拓扑,EIGRP supports 多播(LANs) Point-to-point (HDLC) 非广播式多路访问 (Frame Relay),S0,A,B
