The remote-peer auto-dod-request command configures automatically trigger requests for Label Mapping messages in DoD mode from all downstream remote LDP peers.
The undo remote-peer auto-dod-request command restores the default setting.
By default, the device does not automatically trigger requests for Label Mapping messages in DoD mode from all downstream remote LDP peers.
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.
Precautions
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.
