詞語(yǔ)解釋
PPPoA Point to Point Protocol over ATM ATM點(diǎn)對(duì)點(diǎn)協(xié)議
PPPOA(PPP over ATM)
PPPoA(PPP over ATM)協(xié)議采用PPPoA的接入技術(shù),由PC終端直接發(fā)起PPP呼叫,用戶側(cè)ATM25網(wǎng)卡在收到上層的PPP包后,根據(jù)RFC2364封裝標(biāo)準(zhǔn)對(duì) PPP包進(jìn)行AAL5層封裝處理形成ATM信元流。ATM信元透過(guò)ADSL Modem傳送到網(wǎng)絡(luò)側(cè)的寬帶接入服務(wù)器上,完成授權(quán)、認(rèn)證、分配IP地址和計(jì)費(fèi)等一系列PPP接入過(guò)程。
PPPOA應(yīng)用配置實(shí)例
PPPOA應(yīng)用方式的組網(wǎng)圖和上圖相似,所不同的是以PPPOA代替PPPOEOA。參考配置如下:
注意事項(xiàng):此種方式Client端采用的PAP的認(rèn)證方式,如需采用CHAP認(rèn)證的方式,可在Virtual-Template口下加入如下配置:
ppp chap user aaa
ppp chap password simple aaa
Client的配置:(AR18路由器)
