set protocols erps tcn-propagation
The set protocols erps tcn-propagation command enables sub-ring topology change notifications. When the topology of the sub-ring changes, the FDB refresh of the port will generate a Topology Change (TC) signal. When the tcn-propagation function is enabled, the intersecting node sends an event flush message to the connect ring when it receives the TC signal.
The delete protocols erps tcn-propagation command disables sub-ring topology change notifications.
Command Syntax
set protocols erps tcn-propagation <true | false>
delete protocols erps tcn-propagation
Parameter
Parameter | Description |
<true | false> | Enable or disable topology change notifications. The value could be true or false.
By default, sub-ring topology change notifications is disabled. |
Usage Guidelines
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.
set protocols erps tcn-propagation <true | false>
Example
Enable sub-ring topology change notifications.
