1、MPLS組網(wǎng)案例組網(wǎng)需求：1.各路由器基本信息配置2.OSPF規(guī)范配置，修改網(wǎng)絡(luò)類型為點對點3.所有路由器運行OSPF，RT4?E3/0、RT5?E3/0?network至OSPF中，RT1E3/0重發(fā)布直連到OSPF中4.所有路由器運行MPLS，標簽分發(fā)協(xié)議為LDP5.RT4和RT5運行IBGP，并將E3/1發(fā)布至BGP中IP地址分配如下:前面配置略IGP配置如下：RT1：router?ospf?1?router-id?1.1.1.1?passive-interface?default?no?passive-interface?Serial0/1?no?p
