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