R1GigabitEthernet 0/0/010.1.12.1/24
R1LoopBack 01.1.1.1/32
R2GigabitEthernet 0/0/010.1.12.2/24
R2GigabitEthernet 0/0/110.1.23.2/24
R2LoopBack 02.2.2.2/32
R3GigabitEthernet 0/0/010.1.23.3/24
R4LoopBack 03.3.3.3/32
R1配置：system-view //进入系统视图sysname R1 //修改设备名称isis 1 //进入isis进程is-level level-2 //修改isis级别network-entity 49.0123.0000.0000.0001.00 //配置isis进程的网络实体名称NETinterface GigabitEthernet 0/0/0ip address 10.1.12.1 24isis enable 1 //接口使能isisinterface LoopBack 0ip address 1.1.1.1 32isis enable 1R2配置：system-viewsysname R2isis 1is-level level-2network-entity 49.0123.0000.0000.0002.00interface GigabitEthernet 0/0/0ip address 10.1.12.2 24isis enable 1interface GigabitEthernet 0/0/1ip address 10.1.23.2 24isis enable 1interface LoopBack 0ip address 2.2.2.2 32isis enable 1R3配置：system-viewsysname R3isis 1is-level level-2network-entity 49.0123.0000.0000.0003.00interface GigabitEthernet 0/0/0ip address 10.1.23.3 24isis enable 1interface LoopBack 0ip address 3.3.3.3 32isis enable 1检查现象：配置完成后在R1、R2、R3上查看公网路由表是否有MPLS骨干域路由。执行display ip routing-tablel命令可以看到每台设备上都有MPLS骨干域全网路由。https://5b0988e595225.cdn.sohucs.com/images/20180906/d90d81799a1e4cf796b4e691c8aa4ec3.jpeghttps://5b0988e595225.cdn.sohucs.com/images/20180906/41d02822273149f6ac86bf89c1c802a7.jpeghttps://5b0988e595225.cdn.sohucs.com/images/20180906/45a1ece468624916a6c9f1b214d6cf7a.jpeg2.在MPLS骨干网上配置MPLS基本能力和MPLS LDP，在互联设备的接口上使能MPLS及LDP，建立LSP和实现MPLS报文转发。R1配置：mpls lsr-id 1.1.1.1 //配置LSR的IDmpls //使能MPLSmpls ldp //使能MPLS LDPinterface GigabitEthernet 0/0/0mpls //接口使能MPLSmpls ldp //接口使能MPLS LDPR2配置：mpls lsr-id 2.2.2.2mplsmpls ldpinterface GigabitEthernet 0/0/0mplsmpls ldpinterface GigabitEthernet 0/0/1mplsmpls ldpR3配置：mpls lsr-id 3.3.3.3mplsmpls ldpinterface GigabitEthernet 0/0/0mplsmpls ldp检查现象：配置完成后R1与R2，R2 与R3之间可以建立LDP会话，执行display mpls ldp session命令可以看到显示结果中Status项为“Operational”。 执行display mpls ldp lsp命令，可以看到LDP LSP的建立情况。https://5b0988e595225.cdn.sohucs.com/images/20180906/2456fa27bc9842e7a7f7d22ac3a314fd.jpeghttps://5b0988e595225.cdn.sohucs.com/images/20180906/38487a70aefc45e99f32508589462de6.jpeg下一节，我们将对VPN实例及实例内路由做配置讲解。更多华为数通实验操作敬请关注：誉天教育 QQ：3200569443
