配置EIGRP路由協(xié)議EIGRP協(xié)議概述EIGRP是最典型的平衡混合路由選擇協(xié)議，它融合了距離矢量和鏈路狀態(tài)兩種路由選擇協(xié)議的優(yōu)點(diǎn)，使用散射更新算法，可實(shí)現(xiàn)很高的路由性能。EIGRP特點(diǎn)如下：采用不定期更新，即只在路由器改變計(jì)量標(biāo)準(zhǔn)或拓?fù)涑霈F(xiàn)變化時(shí)發(fā)送部分更新路由。支持可變長(zhǎng)子網(wǎng)掩碼。具有相同的自治系統(tǒng)號(hào)的EIGRP和IGRP之間，可無縫交換路由信息。關(guān)鍵還有：IGRP不支持VLSM和不連續(xù)的子網(wǎng)。EIGRP支持不同的網(wǎng)絡(luò)拓?fù)銭IGRPsupports多播(LANs)Point-to-point(HDLC)非廣播式多路訪問(FrameRelay)S0ABS1EFGHFrame
