ONFIGURATION

MPLS basic capability configuration (required) includes: 

■

Define MPLS LSR ID

■

Disable/enable LDP and enter LDP view

MPLS basic capability configuration (optional) includes:

■

Enable LDP on interface

■

Control LDP loop detection

■

Set LDP session keepalive parameters on interface

Before configuring any other MPLS commands, it is necessary to configure LSR ID 
first. The ID is usually in IP address format and must be unique in the domain. 

Perform the following in the System View. 

By default, LSR ID is not specified. 

To make the MPLS configurations, you must enter the MPLS view first.

Perform the following configuration in the System View, routing protocol view, 
interface view or virtual interface view.

Executing the 

command in the System View will enter the MPLS view.

Executing the 

 command in the interface view will enable the MPLS capability 

on the corresponding interface.

For those link layer protocols that do not support broadcast, such as X.25, Frame 
Relay, ATM, you must use the 

[ ip-mask ] |

default | inarp [ minutes ] } [ broadcast ]

command to configure the 

broadcast attribute to support the transmission of broadcast and multicast 
packets.

This refers to specifying filtering policy as all or ip-prefix.
