The mpls te leaf-list command configures a leaf list for a P2MP TE tunnel. The leaf list allows the ingresses to establish sub-LSPs based on the leaf node addresses.
The undo mpls te leaf-list command deletes the leaf list configured for the P2MP RSVP-TE tunnel.
By default, no leaf list is configured for a P2MP TE tunnel.
| Parameter | Description | Value |

| leaf-list-name |
Specifies the name of a leaf list. The parameter is specified running the mpls te leaf-list command in the system view. |
The name is a string of 1 to 31 case-sensitive characters. The name cannot start with an underscore (_) and when quotation marks are used around the string, spaces are allowed in the string. |
Usage Scenario
VRP supports the way of using a leaf list to manage leaf nodes on a P2MP TE tunnel. When a P2MP TE tunnel is being configured, a leaf list must be specified for the tunnel. This process ensures that the ingress on the tunnel establishes sub-LSPs based on the leaf nodes addresses in the leaf list.
Prerequisites
1.A leaf list has been configured using the mpls te leaf-list command.
2.The tunnel has been switched from the P2P to the P2MP mode using the mpls te p2mp-mode command.<HUAWEI> system-view [~HUAWEI] mpls [*HUAWEI-mpls] mpls te [*HUAWEI-mpls] mpls te p2mp-te [*HUAWEI-mpls] quit [*HUAWEI] mpls te leaf-list iptvch1 [*HUAWEI-mpls-te-leaf-list-iptvch1] destination 2.2.2.2 [*HUAWEI-mpls-te-leaf-list-iptvch1] quit [*HUAWEI] interface Tunnel 10 [*HUAWEI-Tunnel10] tunnel-protocol mpls te [*HUAWEI-Tunnel10] mpls te p2mp-mode [*HUAWEI-Tunnel10] mpls te leaf-list iptvch1
