NOTE: When users want to share the forwarding path of data traffic between intersecting rings, it is important to note that when configuring ERPS, the control VLAN and data VLAN of the intersecting rings should be configured in the same protected instance. For example, let’s assume that two intersecting rings with different control VLANs (such as VLAN 200, VLAN 300), and they share the same data VLAN (such as VLAN 100), it's necessary to configure the control VLANs and data VLAN (VLAN 100, VLAN 200, VLAN 300) into the same protected instance to enable data forwarding between the intersecting rings. You can refer to 1.5 to Example for Configuring ERPS (Intersection Rings) for detailed configuration. |

To enable sub-ring topology change notifications, the following configurations are required:
1. Configure the connect ring for a sub-ring on all intersecting nodes.
set protocols erps ring <ring-id> instance <instance-id> connect ring <ring-id> instance <instance-id>
2. Enable tcn-propagation function to advertise topology changes to the connect ring on all intersecting nodes.
