LDP is the default protocol on Cisco IOS software>
检验MPLS:
show tag tdp blindings
show tag forwarding-bable
show ip cef detail
tracertroute *.*.*.*
三、(可选)配置MTU
Optionally, you may change the maximum>
The default MTU>
The interface MTU is automatically increased on WAN interfaces, but not on LAN interfaces.
Because MTU is not automatically increased on LAN interfaces, you have to increase it
manually using mpls mtu command.
在接口模式下命令mpls mtu bytes,例如:
Router(config-if)#mpls mtu 1512
The minimum MTU is 64 bytes. The maximum depends on the type of interface medium.
