DES-7200 Configuration Guide Chapter 1 MPLS Configuration
1-12
DES-7200(config-if-type ID)#
label-switching
Enable MPLS on an interface.
DES-7200(config-if-type ID)# no
label-switching
Disable MPLS on an interface.
Caution
For the router products, the ip ref command must be used in the interface
configuration mode to enable the router MPLS express forwarding function
and improve the forwarding performance.
1.2.1.4 Enabling LDP on an Interface
After LDP is globally enabled, you should run the mpls ip command in the interface mode to
enable LDP on an interface.
Command Function
DES-7200(config-if-type ID)# mpls ip
Enable LDP on an interface.
DES-7200(config-if-type ID)# no mpls
ip
Disable LDP on an interface.
Caution
After LDP is enabled in the interface mode, the LDP does not take effect on
an interface if the mpls router ldp command is not used in the global
configuration mode to enable LDP. To enable LDP on the interface, you must
also use the label-switching command to enable MPLS on the interface.
1.2.1.5 Configuring MPLS mtu on an Interface
(Optional)
By default, the mtu of MPLS packets that can be transmitted by an interface is the same as the
mtu of the interface. The MPLS mtu determines whether MPLS packets should be fragmented
during the forwarding. The MPLS mtu indicates the overall length of MPLS encapsulation and
encapsulated (such as IP) layers.
Run the no mpls mtu command to restore the default value of the MPLS mtu on an interface.
Command Function
DES-7200(config-if-type ID)# mpls mtu
bytes
Configure the MPLS mtu on an interface.
