Step Command
3. Specify the current device as a master node or
transit node of the primary ring, and specify the
primary port and the secondary port.
ring ring-id node-mode { master | transit }
[ primary-port interface-type interface-number ]
[ secondary-port interface-type interface-number ]
level level-value
4. Specify the current device as the edge node of a
subring, and specify the edge port.
ring ring-id node-mode edge [ edge-port
interface-type interface-number ]
Specifying an assistant-edge node
When configuring an assistant-edge node, you must first configure the primary ring before configuring
the subrings.
Perform this configuration on a device to be configured as an assistant-edge node.
To specify an assistant-edge node:
Step Command
1. Enter system view. system-view
2. Enter RRPP domain view. rrpp domain domain-id
3. Specify the current device as a master node or
transit node of the primary ring, and specify the
primary port and the secondary port.
ring ring-id node-mode { master | transit }
[ primary-port interface-type interface-number ]
[ secondary-port interface-type interface-number ]
level level-value
4. Specify the current device as the assistant-edge
node of the subring, and specify an edge port.
ring ring-id node-mode assistant-edge [ edge-port
interface-type interface-number ]
NOTE:
•
The maximum number of rings that can be configured on a switch in all RRPP domains is 32 in total.
• If a switch carries multiple RRPP rings in an RRPP domain, only one ring can be configured as the
primary ring on the device and the role of the device on a subring can only be an edge node or an
assistant-edge node.
Activating an RRPP domain
IMPORTANT:
To prevent Hello packets of subrings from being looped on the primary ring, enable the primary ring on
its master node before enabling the subrings on their separate master nodes. On an edge node or
assistant-edge node, enable/disable the primary ring and subrings separately:
• Enable the primary ring of an RRPP domain before enabling the subrings of the RRPP domain.
• Disable the primary ring of an RRPP domain after disabling all subrings of the RRPP domain.
To activate an RRPP domain on the current device, enable the RRPP protocol and RRPP rings for the RRPP
domain on the current device.
Perform this operation on all nodes in the RRPP domain.
To activate an RRPP domain:
