【導(dǎo)讀】它融合了IP路由技術(shù)靈活性和ATM交換技術(shù)簡(jiǎn)潔性的優(yōu)點(diǎn)，在面向無連。業(yè)務(wù)，由Cisco、ASCEND、3Com等網(wǎng)絡(luò)設(shè)備大廠所主導(dǎo)。信息，只有局部意義。MPLS包頭的結(jié)構(gòu)如下圖所示，包含20比特的標(biāo)簽，3. 比特的EXP，1比特的S，用于標(biāo)識(shí)此標(biāo)簽是否為最底層標(biāo)簽，轉(zhuǎn)發(fā)，出口邊緣路由器再去掉標(biāo)簽，恢復(fù)原來的IP包。MPLSVPN有三種類型的路由器，CE路由器、PE路由器和P路由器。其中Layer3MPLSVPN遵循RFC2547bis標(biāo)準(zhǔn)，使用。數(shù)據(jù)，因而又稱為BGP/MPLSVPN。級(jí)等）的分組歸為一類，這種類別就稱為轉(zhuǎn)發(fā)等價(jià)類。價(jià)類的分組在MPLS網(wǎng)絡(luò)中將獲得完全相同的處理。來自不同VPN的重疊路由，從而導(dǎo)致某個(gè)站點(diǎn)不可達(dá)。RD具有全局唯一性，通過將8個(gè)字節(jié)的RD. RD和VRF表之間建立了一一對(duì)應(yīng)的關(guān)系。RT的作用類似于BGP中擴(kuò)展團(tuán)體屬性，用于路由信息的分發(fā)。ImportRT和ExportRT，分別用于路由信息的導(dǎo)入、導(dǎo)出策略。
