Set the DR system priority.
drni system-priority
system-priority
By default, the DR system priority is 32768.
Setting the DR role priority of the device
About the DR role priority
DRNI assigns the primary or secondary role to a DR member device based on its DR role priority.
The smaller the priority value, the higher the priority. If the DR member devices in a DR system use
the same DR role priority, the device with the lower bridge MAC address is assigned the primary role.
Restrictions and guidelines
To prevent a primary/secondary role switchover from causing network flapping, avoid changing the
DR priority assignment after the DR system is established.
Procedure
1.
Enter system view.

2.
Set the DR role priority of the device.
drni role priority
priority-value
By default, the DR role priority of the device is 32768.
Configuring DR keepalive settings
Restrictions and guidelines for configuring DR keepalive
settings
Use Layer 3 Ethernet interfaces or management Ethernet interfaces to set up the keepalive link.
Make sure the two ends use the same keepalive settings. DR member devices check the peer
keepalive settings for consistency. If an inconsistency is found, the device will prompt for
configuration revision.
Configuring DR keepalive packet parameters
About DR keepalive packet parameters
Perform this task to specify the parameters for sending DR keepalive packets, such as its source and
destination IP addresses.
The device accepts only keepalive packets that are sourced from the specified destination IP
address. The keepalive link goes down if the device receives keepalive packets sourced from any
other IP address.
Restrictions and guidelines
Make sure the DR member devices in a DR system use the same keepalive destination UDP port.
Procedure
1.
Enter system view.
system-view
2.
Configure DR keepalive packet parameters.
