9.1.3 Configuring a Single-Domain Intersecting-Ring Topology
Configure same ERPS domain at switch 1, switch 2, switch 3 and switch 4. Switch 1, switch 2
and switch 3 consist of ERPS primary ring 1 while switch 2, switch3 and switch 4 consist of
ERPS sub ring 2. Switch 1 is configured as ERPS ring 1 master node and other two switches are
configured as ERPS transit nodes while switch 4 is configured as ERPS ring 2 master node. In
addition switch 2 is configured as edge node and switch 3 is configured as assistant-edge node.
Note:
z
The ports accessing an ERPS ring must be configured as trunk ports, permitting the traffic of
data VLANs to pass through.
z
The ports accessing an ERPS ring must be configured as the members of the control VLAN,
allowing the ERPS packets to be sent and received.
z
STP on ports accessing ERPS rings must be disabled.
z
Only one primary ring is allowed to be configured for each domain.
z
The edge/assistant-edge node of the sub rings must be the intersecting nodes for two rings.
z
The edge/assistant-edge node of the sub rings must be transit node.
z
The common interface must be the intersecting interface for two rings.
z
The edge interface must belong to only one sub ring.
z
Primary and sub rings must only be coexisted in edge/assistant nodes.
z
Primary ring must be created and enabled prior to sub rings.
z
Sub rings must be disabled and removed before primary ring.
z
One switch can only work as master node for a ring and transit node for the other rings
within the same domain.
