The evpn redundancy-mode single-active df-election command configures a device to determine the master/backup status of an ESI instance based on the DF election result in single-active mode.
The undo evpn redundancy-mode single-active command restores the default configuration.
By default, no redundancy mode is configured for an ESI instance. If the evpn redundancy-mode single-active command is run in the system view, the redundancy mode of the ESI instance is single-active. If the evpn redundancy-mode single-active command is not run in the system view, the redundancy mode of the ESI instance is all-active.
Usage Scenario
On a network where a CE is multi-homed to PEs, when the PEs work in single-active mode, one PE is the master PE and the other PEs are the backup PEs. To determine the master/backup status of PEs based on the DF election result, run the evpn redundancy-mode single-active df-election command in single-active mode.
