Function

The remote-ip auto-dod-request command configures automatic triggering of a request to a specified downstream remote LDP peer for a Label Mapping message in DoD mode.

The undo remote-ip auto-dod-request command restores the default setting.

Usage Guidelines

Usage Scenario

On a large-scale network, to reduce the burden on edge devices, use the DoD mode. Because edge devices cannot learn the accurate route to the remote peer, an LDP LSP cannot be set up even if LDP extensions for inter-area LSPs are configured. You can configure the DoD mode in which the local LSR requests a Label Mapping message from a specified downstream LSR or all LSRs to set up an LDP LSP.

To block this function, run the remote-ip auto-dod-request block command.

Precautions

Before running the remote-ip auto-dod-request command, ensure that the following operations has been performed:

Configure a remote LDP session.
Run the longest-match command to configure LDP extensions for inter-area LSPs.
Run the mpls ldp advertisement dod command to set the DoD mode.
