Otherwise, this may causetemporary broadcast storm.z You are recommended not to configure physical-link-state change suppression time on a portaccessing an RRPP ring to accelerate topology convergence. For details, refer to Ethernet PortConfiguration in the Access Volume.Configuring RRPP Nodesz The maximum number of rings that can be configured on a device in all RRPP domains is 16.z If a device carries multiple RRPP rings in an RRPP domain, only one ring can be configured as theprimary ring on the device and the role of the device on a subring can only be an edge node or anassistant-edge node.Specifying a master nodePerform this configuration on a device to be configured as a master node.Follow these steps to specify a master node:To do… Use the command… RemarksEnter system view system-view —Enter RRPP domain view rrpp domain domain-id —Specify the current device asthe master node of the ring, andspecify the primary port and thesecondary portring ring-id node-mode master[ primary-port interface-typeinterface-number ] [ secondary-portinterface-type interface-number ] levellevel-valueRequiredSpecifying a transit nodePerform this configuration on a device to be configured as a transit node.Follow these steps to specify a transit node:
