【導讀】大量HPUXAIXcisco華為學習資料，供大家學習。ciscomplsvpn自學命令與配置手冊...模擬器為原版的Dynamipsi. 順序：R1的F0/0接R2的F0/0，R2的F1/1接R3的F1/1。在這里用lookback接口來。路由器都為最小配置是以上。Dynamips軟件完全模擬所有的實驗。為了使實驗更有價值，所寫實驗均在真實路由器上完。我相信如果我足夠盡力去做的話，我能做任何事情。到mpls的強大的威力。曾經(jīng)有那位兄弟說過一句話：學好mplsvpn與bgp，躺在床上數(shù)。以，當自己重新學習這項技術里，也遇到很多困難。驗與成績記錄下來，給那些學習者一些幫助。在這里主要用到IGP的協(xié)議是opsf與isis,主要是目前只有這兩種協(xié)議支持流量工程。特別是isis，相信大家都知道，這是一種相當實。實用，擴展性差,主要用在企業(yè)。集成ISIS擴展之王，相對復雜。對排錯是相當有幫助的。請喜歡mpls的朋友指出問題，公司邊緣路由器ce是直接與isp邊緣路由器pe相連的。第四步pe1將mp-bgp的路由重分發(fā)進pe-ce的路由協(xié)議中。2020年10月1號前完工。
