<div class="quote"><b>以下是引用<i>风行无际</i>在2006-9-29 0:18:58的发言:</b><br/><p>在NBMA环境下配置OSPF,为什么要在DR(R4)上建立邻居关系呢?命令neighbor IP address</p><p></p><p>请高手指点下,谢谢!~</p></div><p></p><p>我的理解是:在OSPF中,是通过向DR和BDR发送HELLO包,和路由更新包,而在NBMA网络中无法通过泛洪来发送HELLO包,也无没发现邻居,在该拓扑中,如果起104到401和204到402两条PVC,R4适合做DR,因此在R4上手工添加邻居,并设为DR。</p><p>这只是偶的理解,不对的请指出!</p>
