erps ring <ringid> tcn-propogation

Syntax

erps ring <ringid>
        tcn-propogation

Description

This command is to configure a sub-ring interconnection node to pass a topology change notification to the ring instance for the parent ring whenever the topology of the sub-ring changes. The parent ring instance performs a Forwarding Database (FDB) flush and sends a protocol message to ensure that other nodes on the parent ring also perform an FDB flush.

The no form of this command disables topology change notifications.
