Can the MAC address of the bridged virtual interface of a bridge on an AR router be modified


The MAC address of the bridged virtual interface (BVI) of a bridge on an AR router can be modified.
You can run the mac-address command in the Bridge-if interface view to modify the MAC address of the current bridged virtual interface.
The MAC address of a bridged virtual interface is the system MAC address, which may conflict with the MAC addresses of other interfaces or virtual interfaces. If the MAC address of a bridged virtual interface conflicts with the MAC addresses of member interfaces of the bridge group, the bridged virtual interface cannot transmit traffic in Layer 3.
When configuring a bridged virtual interface, confirm whether the MAC address of the interface conflicts with the MAC addresses of the member interfaces of the bridge group. If the MAC addresses conflict, you can run the mac-address command to modify the MAC address of the Bridge-if interface.
After the MAC address of the bridged virtual interface is modified, the device proactively sends a free ARP to update the ARP entries on the peer device.
