When you configure control VLANs for an RRPP domain, you only need to configure the primary control VLAN. The system automatically configures the secondary control VLAN. It uses the primary control VLAN ID plus 1 as the secondary control VLAN ID. For the control VLAN configuration to succeed, make sure the IDs of the two control VLANs are consecutive and have not been assigned yet.

To ensure correct forwarding of RRPPDUs, follow these guidelines:

· Do not configure the default VLAN of a port accessing an RRPP ring as the control VLAN.

· Do not enable QinQ or VLAN mapping on the control VLANs.

After you configure RRPP rings for an RRPP domain, you cannot delete or modify the primary control VLAN of the domain. To do so, use the undo control-vlan command.

Examples

# Configure VLAN 100 as the primary control VLAN of RRPP domain 1 (assume that VLAN 100 and VLAN 101 have not been created yet).

domain ring

Use domain ring to configure subrings for an RRPP ring group.

Use undo domain ring to remove subrings from the RRPP ring group.

Syntax

domain domain-id ring ring-id-list

undo domain domain-id [ ring ring-id-list ]

Default

No subring exists in the RRPP ring group.

Views

RRPP ring group view

Predefined user roles

network-admin

Parameters

domain-id: Specifies an RRPP domain by its ID in the range of 1 to 128.

ring ring-id-list: Specifies a space-separated list of up to 10 RRPP subring ID items. Each item specifies an RRPP subring ID or a range of RRPP subring IDs. The value range for RRPP subring IDs is 1 to 128. If you do not specify this option, the command removes all subrings from the ring group in the specified domain.

Usage guidelines

Follow these guidelines when you configure an RRPP ring group on the edge node and the assistant edge node:

· When you assign an active ring to a ring group, assign it on the assistant edge node first and then on the edge node.

· To remove an active ring from a ring group, remove it on the edge node first and then on the assistant edge node.

· To remove the whole ring group, remove it on the edge node first and then on the assistant edge node.

· When you activate rings in a ring group, activate them on the edge node first and then on the assistant edge node.

· When you deactivate rings in a ring group, deactivate them on the assistant edge node first and then on the edge node.

If you do not follow these guidelines, the assistant edge node might fail to receive Edge-Hello packets and consider the primary ring failed even if it did not.

Examples

# Create RRPP ring group 1, and add subrings 1, 2, 3, and 5 to domain 1 and domain 2.

<Sysname> system-view

[Sysname] rrpp ring-group 1

Default

Parameters

reference-instance instance-id-list: Specifies the Multiple Spanning Tree Instances (MSTIs) you want to reference in the form of instance-id-list = { instance-id [ to instance-id ] }&<1-10>. The instance-id argument is an MSTI ID in the range of 0 to 4094. You can specify up to 10 MSTI IDs or ID ranges. You can use the display stp region-configuration command to display the VLAN-to-instance mappings. If you do not specify this option, the command removes all MSTIs referenced by the RRPP domain.

Usage guidelines

You can delete or modify the protected VLANs configured for an RRPP domain before and after you configure rings for it. However, you cannot delete configurations of all the protected VLANs configured for the domain.

When the VLAN-to-instance mappings change, the protected VLANs of an RRPP domain also change.

Examples

# Map VLANs 1 through 30 to MSTI 1, and activate the MST region configuration. Configure VLAN 100 as the control VLAN of RRPP domain 1. Configure VLANs mapped to MSTI 1 as the primary control VLANs of RRPP domain 1.

Parameters

ring-id: Specifies an RRPP ring by its ID in the range of 1 to 128.

master: Specifies the device as the master node of the RRPP ring.

transit: Specifies the device as the transit node of the RRPP ring.

primary-port: Specifies the port as a primary port.

interface-type interface-number: Specifies a port by its type and number.

secondary-port: Specifies the port as a secondary port.

level level-value: Specifies an RRPP ring level, 0 for the primary ring and 1 for the subring.

assistant-edge: Specifies the device as the assistant edge node of the RRPP ring.

edge: Specifies the device as the edge node of the RRPP ring.

edge-port: Specifies the edge port for the node.

Usage guidelines

The ID of an RRPP ring in a domain must be unique.

When an RRPP ring is activated, you cannot configure its RRPP ports.

When you configure the edge node and the assistant edge node, first configure the primary ring, and then the subrings.

The node mode, RRPP port role, and ring level settings of an RRPP ring cannot be modified after they are configured. To modify the settings, first remove the current settings.

Remove all subring configurations before you delete the primary ring configuration of the edge node or the assistant edge node. However, an active RRPP ring cannot be deleted.

When RRPP is enabled on a device, you must disable the RRPP ring before you can delete it. When RRPP is disabled on the device, you can directly delete the RRPP ring, as well as the setting of the ring enable command.

Examples

# Specify the device as the master node of primary ring 10 in RRPP domain 1. Specify FortyGigE 1/1/1 as the primary port and FortyGigE 1/1/2 as the secondary port.
