# mpls topology-driven-lsp

#### Syntax

[ no ] mpls topology-driven-lsp

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Enables topology-driven LSP creation on the virtual router where the LSR automatically creates LSPs when it learns a new IGP route. In the context of the VRF virtual router, enables carrier-of-carriers support on the provider carrier's PE router.

The router advertises labels for new routes immediately to all peers without waiting for a label request message from an upstream peer or a label mapping message from a downstream peer. This mode is downstream-unsolicited, independent control.

The no version disables topology-driven LSPs on the virtual router.

#### Mode

Global Configuration
