Parameter Description: MPLS

Parameter Description: MPLS

This topic describes the parameters related to MPLS.

Basic Configuration

Basic MPLS configuration focuses on setting of equipment LSR IDs.

Table 3-332 lists parameters for basic MPLS configuration.

Table 3-332  Parameter for basic MPLS configuration

Parameter

Value Range

Description

LSR ID

Example: 10.70.73.156

In a packet switched network (PSN), one NE must be allocated with a unique LSR ID.

When planning the LSR ID for an NE, adhere to the following principles:

  • The IP address of an NNI port can be an IP address of standard class A, B, or C (namely, an IP address within the range from 1.0.0.1 to 223.255.255.254). The IP address of an NNI port cannot be a broadcast address (*.*.*.255), multicast address (224.0.0.0 to 239.255.255.255), reserved address (240.0.0.0 to 255.255.255.255), network address (*.*.*.0), zero address (0.*.*.*), loopback address (127.*.*.*). The address of the network segment used with priority: 172.16.0.0-172.31.255.255. In this network segment, the number of the available IP address is 1048574 (the 172.16.0.0 and 172.31.255.255 are exceptional).
  • Each NE must have an independent and globally unique LSR ID on a network.
  • The LSR ID of an NE and the IP address of the NE must be different from each other and must be in different network segments.
  • The SLR ID of an NE must be in a different network segment from the IP address of any service port on the NE.

After setting LSR IDs, enable the MPLS function. Otherwise, other functions of the MPLS network cannot be set.
