(Optional) Creating a Ring Group

(Optional) Creating a Ring Group


To reduce the number of received and sent Edge-Hello packets, you can use a ring group, in which a group of sub-rings with the same configuration of edge nodes or assistant edge nodes are added to the ring group.


  1. On the edge node or assistant edge node, run system-view

    The system view is displayed.

  2. Run rrpp ring-group ring-group-id

    A ring group is created.

    A ring group can be created only on an edge node or an assistant edge on a sub-ring.

    All the sub-rings in a ring group must be on nodes of the same type, for example, all the sub-rings are located on edge nodes or assistant edge nodes.

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

    Sub-rings are added to the ring group.

    Sub-rings in the same ring group share the same edge node, and the same assistant edge node.

    A sub-ring can belong to only one ring group.

    When you add a sub-ring to a ring group or delete a sub-ring from the ring group, note the following points:

    • 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.
