1、聯(lián)邦解析
成都創(chuàng)新互聯(lián)是一家專業(yè)提供龍州企業(yè)網(wǎng)站建設(shè),專注與網(wǎng)站設(shè)計、成都網(wǎng)站設(shè)計、H5網(wǎng)站設(shè)計、小程序制作等業(yè)務(wù)。10年已為龍州眾多企業(yè)、政府機構(gòu)等服務(wù)。創(chuàng)新互聯(lián)專業(yè)網(wǎng)站制作公司優(yōu)惠進行中。
聯(lián)邦工作原理:在AS內(nèi)部手動劃分多個私有AS(聯(lián)邦中的私有AS好不增加AS-PATH的路徑長度)
配置步驟:
第一步:router bgp 小AS號(私有AS號)
第二步:聲明所在大AS號
第三步:小AS號之間互指peer
