(3) Configuration with a shared link non-monitoring master node on the shared link
If a shared link consists of three or more nodes, the shared link non-monitoring master node cannot be a node
on the shared link.
Figure 4.1-3 Configuration when a shared link consists of multiple nodes
(4) Ring configuration with a loop
You cannot configure a multi-ring that has any loop.
Figure 4.1-4 Ring configuration with a loop
The master node in the shared link
monitoring ring monitors the shared
link, so you cannot place a shared
link non-monitoring master node on
the shared link.
If the node on the shared link is eithe
r
a shared link monitoring master node
or transit node, the node has no
impact on the shared link.

A loop exists here.
In a VLAN-shared
multi-ring, a loop occurs if
you place multiple single
rings and connect transit
nodes without configuring
any shared links.
In this case, you must
change the loop network to
another ring and configure a
multi-ring configuration with
shared links that has the
shared link monitoring and
