R4（config-router）#network4.4.4.40.0.0.0area0

------------------------------------------------------------------------

3.配置MPLS

------------------------------------------------------------------------

查看MPLS标签数量

R1#showmplslabelrange

DownstreamGenericlabelregion:

Min/Maxlabel:

16/100000

//最小16,最大100000

修改标签的范围

R1（config）#mplslabelrange100200

R2（config）#mplslabelrange201300

R3（config）#mplslabelrange301400

R4（config）#mplslabelrange401500

------------------------------------------------------------------------

查看接口MTU

------------------------------------------------------------------------

R1#showmplsinterfacesfastEthernet0/0detail

InterfaceFastEthernet0/0:

IPlabelingenabled（ldp）:

Interfaceconfig

LSPTunnellabelingnotenabled

BGPtaggingnotenabled

Taggingoperational

FastSwitchingVectors:

IPtoMPLSFastSwitchingVector

MPLSTurboVector

MTU=1500

------------------------------------------------------------------------

修改接口MTU

------------------------------------------------------------------------

R1（config）#intf0/0

R1（config-if）#mplsmtu1508

R1#showmplsinterfacesfastEthernet0/0detail

InterfaceFastEthernet0/0:

IPlabelingenabled（ldp）:

Interfaceconfig

LSPTunnellabelingnotenabled

BGPtaggingnotenabled

Taggingoperational

FastSwitchingVectors:

IPtoMPLSFastSwitchingVector

MPLSTurboVector

MTU=1508

------------------------------------------------------------------------

3.配置LDP

------------------------------------------------------------------------

全局开启CEF

------------------------------------------------------------------------

R1（config）#ipcef

R2（config）#ipcef

R3（config）#ipcef

R4（config）#ipcef

R1（config）#mplslabelprotocolldp//标签分发协议LDP

R1（config）#mplsldprouter-idloopback0force//LDP协议ID使用loopback0地址

R1（config）#interfacefastEthernet0/0

R1（config-if）#mplsip//在接口下运行mpls

R2（config）#mplslabelprotocolldp

R2（config）#mplsldprouter-idloopback0force

R2（config）#interfacefastethernet0/0

R2（config-if）#mplsip

R2（config）#interfaceFastEthernet0/1

R2（config-if）#mplsip

R3（config）#mplslabelprotocolldp

R3（config）#mplsldprouter-idloopback0force

R3（config）#interfaceFastEthernet0/0

R3（config-if）#mplsip

R3（config）#interfaceFastEthernet0/1

R3（config-if）#mplsip

R4（config）#mplslabelprotocolldp

R4（config）#mplsldprouter-idloopback0force

R4（config）#interfaceFastEthernet0/0

R4（config-if）#mplsip

检查mpls接口运行状态

R1#showmplsinterfaces

InterfaceIPTunnelOperational

FastEthernet0/0Yes（ldp）NoYes

R2#showmplsinterfaces

InterfaceIPTunnelOperational

FastEthernet0/0Yes（ldp）NoYes

FastEthernet0/1Yes（ldp）NoYes

R3#showmplsinterfaces

InterfaceIPTunnelOperational

FastEthernet0/0Yes（ldp）NoYes

FastEthernet0/1Yes（ldp）NoYes

R4#showmplsinterfaces

InterfaceIPTunnelOperational

FastEthernet0/0Yes（ldp）NoYes
