• The Control VLAN cannot have members that are not ring ports.
• If multiple rings share one or more member VLANs, they cannot share any links between them.
• Member VLANs across multiple rings are not supported in Master nodes.
• Each ring has only one Master node; all others are transit nodes.
Configuring FRRP
These are the tasks to configure FRRP.
• Creating the FRRP group
• Configuring the Control VLAN
• Configuring Primary and Secondary ports
• Configuring and adding the Member VLANs
• Configuring Primary and Secondary ports
• Configuring the Master node
• Configuring a Transit node

Creating the FRRP group
The FRRP group must be created on each switch in the ring.
Use the commands in the following sequence to create the FRRP group.
Configuring the Control VLAN
Control and Member VLANS are configured normally for Layer 2. Their status as Control or Member is
determined at the FRRP group commands. For complete information about configuring VLANS in Layer 2
mode, refer to Layer 2.
Be sure to follow these guidelines:
• All VLANS must be in Layer 2 mode.
• Only ring nodes can be added to the VLAN.
• A Control VLAN can belong to one FRRP group only.
