New message

Similar to a Join message, a New message enables MRP participants to register attributes.

When the MSTP topology changes, an MRP participant sends a New message to the peer participant to declare the topology change.

Upon receiving a New message from the peer participant, an MRP participant performs the following tasks:

• Registers the attributes in the message.
• Propagates the New message to all other participants on the device.

After receiving the New message, other participants send the New message to their respective peer participants.
