Configuring the Limit Rate of MPLS TE Traffic

This section describes how to configure the limit rate of MPLS TE traffic to limit TE tunnel traffic within the bandwidth range that is actually configured.

Usage Scenario

For a physical link of a TE tunnel, besides traffic on the TE tunnel, the physical link may carry MPLS traffic of other TE tunnels, MPLS traffic of other non-CR-LSPs, or even IP traffic simultaneously. To limit the TE tunnel traffic within a bandwidth range that is actually configured, set a limit rate for TE tunnel traffic.

After the configuration of the limit rate, TE traffic is limited to a bandwidth range that is actually configured. TE traffic with the bandwidth higher than the set bandwidth is dropped.

Before you configure rate limiting for MPLS TE traffic, run the mpls te bandwidth command on the corresponding tunnel interface. If this command is not run, rate limiting is not performed for MPLS TE traffic.

Pre-configuration Tasks

Before configuring rate limiting for MPLS TE traffic, complete the following tasks:

Configure a static CR-LSP or an RSVP-TE tunnel

Procedure

Run system-view
The system view is displayed.
Run interface tunnel tunnel-number
The tunnel interface view is displayed.
Run mpls te bandwidth ctType ctValue
The bandwidth constraint of the MPLS TE tunnel is configured.
Run mpls te lsp-tp outbound
Traffic policing for the SR-MPLS TE tunnel is enabled.
Run commit
The configuration is committed.

Verifying the Configuration

Run the display current-configuration interface Tunnel tunnel-number command. The command output shows that the rate limit function has been enabled.
