9.4 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:
• The ports accessing an ERPS ring must be configured as trunk ports, permitting
the traffic of data VLANs to pass through.
• 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.
• STP on ports accessing ERPS rings must be disabled.
• Only one primary ring is allowed to be configured for each domain.
• The edge/assistant-edge node of the sub rings must be the intersecting nodes for
two rings.
• The edge/assistant-edge node of the sub rings must be transit node.
• The common interface must be the intersecting interface for two rings.
• The edge interface must belong to only one sub ring.
• Primary and sub rings must only be coexisted in edge/assistant nodes.
• Primary ring must be created and enabled prior to sub rings.
• Sub rings must be disabled and removed before primary ring.
• One switch can only work as master node for a ring and transit node for the other
rings within the same domain.
