the VLANs mapped to MSTI 1 as the protected VLANs of RRPP domain 1.

Device D.
Troubleshooting
Symptom
When the link state is normal, the master node cannot receive Hello packets, and the master node
unblocks the secondary port.
Analysis
The reasons may be:
• RRPP is not enabled on some nodes in the RRPP ring.
• The domain ID or primary control VLAN ID is not the same for the nodes in the same RRPP ring.
• Some ports are abnormal.
Solution
• Use the display rrpp brief command to check whether RRPP is enabled for all nodes. If it is not, use
the rrpp enable command and the ring enable command to enable RRPP and RRPP rings for all
nodes.
• Use the display rrpp brief command to check whether the domain ID and primary control VLAN ID
are the same for all nodes. If they are not, set the same domain ID and primary control VLAN ID for
the nodes.
• Use the display rrpp verbose command to check the link state of each port in each ring.
• Use the debugging rrpp command on each node to check whether a port receives or transmits
Hello packets. If it does not, Hello packets are lost.
