Note: Sub-Rings use MRP. You can couple Sub-Rings to existing primary
rings with the HIPER-Ring protocol, the Fast HIPER-Ring protocol and MRP.
If you couple a Sub-Ring to a primary ring under MRP, configure both rings
in different VLANs. You configure
X either the Sub-Ring Managers’ Sub-Ring ports and the devices of the
Sub-Ring in a separate VLAN. Here multiple Sub-Rings can use the same
VLAN.

or the devices of the primary ring including the Sub-Ring Managers’
primary ring ports in a separate VLAN. This reduces the configuration
effort when coupling multiple Sub-Rings to a primary ring.
3.1.1 Example configuration
The following section shows in detail the configuration of a simple Sub-Ring
example.

Example description
You want to couple a new network segment with 3 devices to an existing
redundant ring with the HIPER-Ring protocol. If you couple the network at
both ends instead of only one end, this provides increased availability with
the corresponding configuration.
The new network segment will be coupled as a Sub-Ring. The coupling to
the primary ring is performed by existing devices of the type
Configure these devices as Sub-Ring Managers.
