Configuring DR system settings
Configuring the DR system MAC address
Restrictions and guidelines
Changing the DR system MAC address causes DR system split. When you perform this task on a
live network, make sure you are fully aware of its impact.
The DR system MAC address uniquely identifies the DR system on the network. For the DR member
devices to be identified as one DR system, you must configure the same DR system MAC address
on them. As a best practice, use the bridge MAC address of one DR member device as the DR
system MAC address.
Procedure
1. Enter system view.
system-view
2. Configure the DR system MAC address.
drni system-mac mac-address
By default, the DR system MAC address is not configured.
