evpn redundancy-mode

Function

The evpn redundancy-mode command sets a redundancy mode for an ESI instance.

The undo evpn redundancy-mode command cancels the redundancy mode for an ESI instance.

By default, if the evpn redundancy-mode single-active command is run in the system view, the redundancy mode of an ESI instance is single-active; if the evpn redundancy-mode single-active command is not run, the redundancy mode of an ESI instance is all-active.

Format

evpn redundancy-mode { single-active | all-active }

undo evpn redundancy-mode { single-active | all-active }

Usage Guidelines

Usage Scenario

In scenarios where different CEs are dual-homed to PEs, if you want a remote PE to send unicast traffic to different CEs in different modes (load balancing and non-load balancing), you can set a redundancy mode per ESI instance. Before performing this configuration, you need to confirm the ESI generation mode on the access side and then create a dynamic or static ESI instance based on the ESI generation mode. Each dynamic or static ESI instance corresponds to a unique ESI on the access side. Therefore, you can run the evpn redundancy-mode { single-active | all-active } command in a dynamic or static ESI instance to set a redundancy mode for the corresponding ESI.

Precautions

If the evpn redundancy-mode single-active command is run on an ESI, the ESI cannot be configured in a BD where UMR is enabled.
If an ESI has been configured in a BD with UMR enabled, the ESI cannot be configured with evpn redundancy-mode single-active.

Example

# Set the redundancy mode of a dynamic ESI instance to all-active.

<HUAWEI> system-view
[~HUAWEI] evpn
[*HUAWEI-evpn] esi dynamic-name esi1
[*HUAWEI-evpn-esi-dynamic-esi1] evpn redundancy-mode all-active

# Set the redundancy mode of a static ESI instance to single-active.

<HUAWEI> system-view
[~HUAWEI] evpn
[*HUAWEI-evpn] esi 0011.1001.1001.1001.1002
[*HUAWEI-evpn-esi-0011.1001.1001.1001.1002] evpn redundancy-mode single-active
