理論學(xué)習(xí)
問(wèn)題1：EIGRP的特點(diǎn)？
EIGRP是一種內(nèi)部網(wǎng)關(guān)協(xié)議，用在自制系統(tǒng)的內(nèi)部執(zhí)行路由功能，為無(wú)類路由協(xié)議，性質(zhì)為高級(jí)距離矢量路由協(xié)議
與運(yùn)行EIGRP的路由器之間通過(guò)發(fā)送Hello包形成鄰居關(guān)系后交換路由信息。
運(yùn)行EIGRP的路由器儲(chǔ)存所有與其相鄰路由器的路由表信息
EIGRP采用組播和單播的更新方式，只有在路由器改變計(jì)量標(biāo)準(zhǔn)或拓?fù)浒l(fā)生變化的情況下進(jìn)行路由更新
支持可變長(zhǎng)子網(wǎng)掩碼和不連續(xù)的子網(wǎng)，支持路由自動(dòng)匯總，支持多種網(wǎng)絡(luò)層協(xié)議還支持IPX,AppleTake等
在運(yùn)行EIGRP的路由器內(nèi)部，有一個(gè)鄰居路由表，一個(gè)拓?fù)浣Y(jié)構(gòu)表和一個(gè)路由表。
使用DUAL算法，具有很好的路由收斂特性。
支持任意負(fù)載均衡。
問(wèn)題2：EIGRP的運(yùn)行過(guò)程？
建立相鄰關(guān)系
發(fā)現(xiàn)網(wǎng)絡(luò)拓?fù)?，選擇最短路由
路由查詢、更新
問(wèn)題3：EIGRP與RIP的區(qū)別？
EIGRP是思科專有的，而RIP是通用的協(xié)議
EIGRP是高級(jí)距離矢量協(xié)議 RIP是距離矢量協(xié)議
工作任務(wù)實(shí)施

問(wèn)題1：自動(dòng)匯總和手動(dòng)匯總的區(qū)別？
自動(dòng)方式：當(dāng)路由中存在多個(gè)交叉的小分類網(wǎng)絡(luò)邊界時(shí)自動(dòng)把這些路由匯總成一個(gè)大的分類網(wǎng)絡(luò)邊界（這是通過(guò)匯總子網(wǎng)地址前綴來(lái)實(shí)現(xiàn)的）。自動(dòng)匯總功能是默認(rèn)啟用的。
手動(dòng)方式：在指定接口上通告一個(gè)匯總本地IP地址池，這個(gè)匯總IP地址池可以供撥號(hào)客戶端。
