The mpls te p2mp-te disable command disables the P2MP TE capability on a specific interface.
The undo mpls te p2mp-te disable command restores the default P2MP TE capability.
By default, the P2MP TE capability on a specific interface of a node is the same as that configured globally on the node.

Usage Scenario
By default, after P2MP TE is globally enabled, P2MP TE is automatically enabled on each MPLS TE-enabled interface on a local node. To disable P2MP TE on a specific interface during network planning or there is no need to have P2MP TE enabled on a specific interface because it does not support P2MP forwarding, run the mpls te p2mp-te disable command on that interface.
Prerequisites
MPLS TE has been enabled using the mpls te command on the interface.
Configuration Impact
After the mpls te p2mp-te disable command is run, P2MP TE LSPs established on the interface are torn down, and newly configured P2MP TE LSPs on the interface fail to be established.
If a computed optimal path for a TE tunnel passes through the existing interface, the TE LSP cannot be established. To prevent such a failure, plan an explicit path that excludes this interface.<HUAWEI> system-view [~HUAWEI] mpls [*HUAWEI-mpls] mpls te [*HUAWEI-mpls] mpls te p2mp-te [*HUAWEI-mpls] quit [*HUAWEI] interface GigabitEthernet 0/1/0 [*HUAWEI-GigabitEthernet0/1/0] mpls [*HUAWEI-GigabitEthernet0/1/0] mpls te [*HUAWEI-GigabitEthernet0/1/0] mpls te p2mp-te disable
