The ospf ti-lfa disable command disables TI-LFA on an OSPF interface.
The undo ospf ti-lfa disable command enables TI-LFA on an OSPF interface.
By default, TI-LFA is enabled automatically on OSPF interfaces if the ti-lfa enable command is run.

Usage Scenario
After the ti-lfa enable command is run, TI-LFA is automatically enabled on all OSPF interfaces. To disable TI-LFA on a specified interface, run the ospf ti-lfa disable command in the interface view.
Precautions
If the ti-lfa enable command is not run, the ospf ti-lfa disable multi-area command can be run but cannot take effect on an interface.
If the ospf ti-lfa disable and ti-lfa enable commands are run in sequence, the ospf ti-lfa disable multi-area command still takes effect. If an interface is bound to a VPN instance, the interface does not support TI-LFA.<HUAWEI> system-view [~HUAWEI] segment-routing [*HUAWEI-segment-routing] quit [*HUAWEI] ospf 1 [*HUAWEI-ospf-1] opaque-capability enable [*HUAWEI-ospf-1] segment-routing mpls [*HUAWEI-ospf-1] quit [*HUAWEI] interface GigabitEthernet 0/1/0 [*HUAWEI-GigabitEthernet0/1/0] ospf ti-lfa disable multi-area 1
