EIGRP 非等價(jià)負(fù)載均衡

1、eigrp 非等價(jià)負(fù)載均衡eigrp 既支持等價(jià) 也支持非等價(jià)負(fù)載均衡 下面做非等價(jià)負(fù)載均衡 650) this.wth=650;" src="/uploads/allimg/111214/12551l463-0.gif" border="0" alt="" /> 首先要滿足的是要有fs 假如惟獨(dú)cceesor 沒(méi)有fs 那么就不會(huì)產(chǎn)生非等價(jià)不在均衡 非等價(jià)負(fù)載均衡主要是調(diào)variae值 variance值*fs的fd successor的fd就可以了。 從上面的拓?fù)鋱D很簡(jiǎn)單看出去往1.1.1.1這個(gè)網(wǎng)段絕對(duì)是走以太網(wǎng)
