實驗一：MPLS配置

實驗環(huán)境：三臺路由器Ethernet接口相連，接口配苴如圖

Rl(config-if)#ipadd100.1.I.1255.255.255.0今指定【P地址,兩端要在一個網(wǎng)段

RI(config-if)tttunnclsourcesO指定承載隧道的源和目的接口

RI(config-if)tttunneldestinationJO.1.1.2

RI(config-if)ttnosh

Rl(config)#iproute40.1.1,0255.255.255.0LunnelO今為私有網(wǎng)絡(luò)指路由走tunnel

接口

R3(config)ttinttunnel0

R3(config-if)?ipadd100.1.1,2255.255.255.0

R3(config-if)#tunnelsourcesi互指源和H的

R3(config-if)tttunne1destination20.1.1.I

R3(config-if)#nosh

R3(config-if)#exit

R3(config)#iproute10.1.1.0255.255.255.0tunnel0今指對端的私有網(wǎng)絡(luò)

步驟四：做PING測試
