The multicast frr revert disable command disables multicast FRR switchback.
The undo multicast frr revert disable command enables multicast FRR switchback.
By default, multicast FRR switchback is enabled.
Usage Scenario
In a multicast FRR scenario, a device with the default FRR configuration rapidly switches traffic on a secondary link back to a primary link when the primary one recovers. Multicast FRR switchback, however, is not recommended for ring networks, because the device fails to receive traffic from a secondary link if a switchover is performed again in a short time after a switchback. To disable multicast FRR switchback, run the multicast frr revert disable command.
