/*The following command configures protection instance 1 for the ERPS domain:*/
Switch_C(config)#set ERPS domain 1 protect-instance 1
/*The following command configures switch C to be a none node: */
Switch_C(config)#set ERPS domain 1 ring-id 1 raps-vlan 4000 ring-east port 1/1
ring-west port 1/2
The configuration on switch D is as follows:
/*The following commands configure a spanning tree instance:*/
Switch_D(config)#set stp enable
Switch_D(config)#set stp instance 1 add vlan 100-110
/*The following command configures protection instance 1 for the ERPS domain:*/
Switch_D(config)#set ERPS domain 1 protect-instance 1
/*The following command configures switch D to be a none node: */
Switch_D(config)#set ERPS domain 1 ring-id 1 raps-vlan 4000 ring-east trunk

single-ring, multiple-domain. The configuration is as follows:
l
Protection instance 1 is configured for ERPS domain 1. In this instance, the dedicated
VLAN (VLAN 4000) protects VLANs 100 to 110. Protection instance 2 is configured for
ERPS domain 2. In this instance, the dedicated VLAN (VLAN 4001) protects VLANs
200 to 210.
l
Switch A is an owner node in domain 1 (the related ports are ports 1/1 and 1/2, where
port 1/2 is an RPL port), and it is a neighbor node in domain 2 (the related ports are
ports 1/1 and 1/2, where port 1/2 is also an RPL port).
l
Switch B is a neighbor node in domain 1 (the related ports are port 1/1 and port 1/2,
where port 1/2 is an RPL port), and it is an owner node in domain 2 (the related ports
are ports 1/1 and 1/2, where port 1/2 is also an RPL port).
l
Both switches C and D are none nodes in domains 1 and 2.
Note:
If a physical ring has multiple ERPS domains, you can plan different paths for the service
traffic related to different ERPS domains through the proper configuration, so that load
balancing can be implemented.
