domain (RRPP ring group view)

Function

The domain command adds sub-rings to an RRPP ring group.

The undo domain command deletes the sub-rings from the RRPP ring group.

domain domain-id ring { ring-id1 [ to ring-id2 ] } &<1-10>

undo domain domain-id ring { ring-id1 [ to ring-id2 ] } &<1-10>

Parameter	Description	Value
domain-id	Specifies the ID of an RRPP domain.	The value is an integer that ranges from 1 to 64.
ring ring-id1 to ring-id2	Specifies the ID of an RRPP sub-ring. ring-id1 specifies the first sub-ring ID. to ring-id2 specifies the last sub-ring ID. The value of ring-id2 must be larger than the value of ring-id1. ring-id1 and ring-id2 identify a range of instances. If to ring-id2 is not specified, only ring-id1 is specified.	The value is an integer that ranges from 1 to 64.

Usage Scenario

If multiple RRPP rings exist, you can add sub-rings to the ring group to reduce the number of Edge-Hello packets, improving system performance.

Precautions

A maximum of 15 sub-rings can be added to a ring group.

If the domain command is run more than once, all configurations take effect.

Only an edge node or an assistant edge node on a sub-ring can be added to a ring group. The edge nodes on the sub-rings are configured on the same device. Similarly, the assistant edge nodes are on the same device.
A sub-ring can belong to only one ring group.
All the sub-rings in a ring group must be on the same type of nodes, that is, edge nodes or assistant edge nodes.
To add an activated sub-ring to a ring group, add the sub-ring to the ring group on the assistant edge node, and then perform the same operation on the edge node.
To delete an activated sub-ring from a ring group, delete the sub-ring from the ring group on the edge node, and then perform the same operation on the assistant edge node.
All the sub-rings in a ring group must have the same primary ring link; otherwise, the ring group cannot work properly.
The configuration and activation status of a ring group must be the same on the edge node and assistant edge node.
