The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of RRPP.

General restrictions and guidelines

When you configure RRPP, follow these restrictions and guidelines:

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

· On swiches that support QinQ and VLAN mapping, do not enable QinQ or VLAN mapping on control VLANs. If you do, RRPPDUs cannot be correctly forwarded.

· On swiches that support Layer 3 Ethernet interfaces, the primary and secondary control VLAN IDs must be different from the Layer 3 Ethernet subinterface IDs of the master ring and subrings.

· To prevent temporary broadcast storms, do not enable the OAM remote loopback feature on an RRPP port.

Example: Configuring a single ring

Network configuration

As shown in Figure 1, area A and area B are connected to a ring-shaped distribution layer network. Configure RRPP to implement the following requirements in the network:

· Eliminate loops and implement link recovery in the Layer 2 network.

· Implement link load balancing by forwarding voice traffic in VLAN 100 through VLAN 150 and video traffic in VLAN 151 through VLAN 200.

· Improve RRPP topology convergence speed by setting the physical state change suppression interval to 0 seconds for all Ethernet interfaces on the RRPP ring.

Figure 1 Network diagram

Analysis

For voice and video traffic to be forwarded in different topologies, create two RRPP domains.

· In RRPP domain 1, specify VLAN 100 through VLAN 150 as protected VLANs, and specify Device A as the master node.

· In RRPP domain 2, specify VLAN 151 through VLAN 200 as protected VLANs, and specify Device B as the master node.

To implement load balancing for voice and video traffic, perform the following tasks:

· On Device A, specify GigabitEthernet 1/0/1 as the primary port, and GigabitEthernet 1/0/2 as the secondary port.

· On Device B, specify GigabitEthernet 1/0/2 as the primary port, and GigabitEthernet 1/0/1 as the secondary port.

Restrictions and guidelines

When you configure a single RRPP ring, follow these restrictions and guidelines:

· After you configure RRPP rings for an RRPP domain, you cannot delete or modify the primary control VLAN of the domain. You can only use the undo control-vlan command to delete a primary control VLAN.

· When you configure load balancing, you must configure different protected VLANs for different RRPP domains.

· When you configure RRPP port roles, disable the spanning tree feature on the ports, and make sure the ports are not member ports of any smart link groups.

Example: Configuring intersecting rings

Network configuration

As shown in Figure 3, a ring-shaped access layer network is connected to a ring-shaped distribution layer network. Configure RRPP to implement the following requirements in the network:

· Eliminate loops and implement link recovery in the Layer 2 network.

· Implement link load balancing by forwarding voice traffic in VLAN 100 through VLAN 150 and video traffic in VLAN 151 through VLAN 200.

· Improve RRPP topology convergence speed by setting the physical state change suppression interval to 0 seconds for all Ethernet interfaces on the RRPP ring.

Figure 3 Network diagram

Analysis

For voice and video traffic to be forwarded in different topologies, create two RRPP domains.

· In RRPP domain 1, specify VLAN 100 through VLAN 150 as protected VLANs. Specify Device A as the master node of primary ring 1, and Device E as the master node of subring 2.

· In RRPP domain 2, specify VLAN 151 through VLAN 200 as protected VLANs. Specify Device B as the master node of primary ring 1, and Device F as the master node of subring 2.

To implement load balancing for voice and video traffic, perform the following tasks:

· On Device A, specify GigabitEthernet 1/0/1 as the primary port, and GigabitEthernet 1/0/2 as the secondary port.

· On Device B, specify GigabitEthernet 1/0/2 as the primary port, and GigabitEthernet 1/0/1 as the secondary port.

· On Device E, specify GigabitEthernet 1/0/2 as the primary port, and GigabitEthernet 1/0/1 as the secondary port.

· On Device F, specify GigabitEthernet 1/0/1 as the primary port, and GigabitEthernet 1/0/2 as the secondary port.

Restrictions and guidelines

When you configure intersecting rings, follow these restrictions and guidelines:

· When you configure an edge node or assistant edge node, you must configure the primary ring before configuring the subrings.

· When you configure load balancing, you must configure different protected VLANs for different RRPP domains.

· Before you enable subrings on a device, you must enable the primary ring. Before you disable the primary ring on the device, you must disable all subrings.

· If a device carries multiple RRPP rings in an RRPP domain, it can only be an edge node or an assistant edge node on a subring.

· To prevent Hello packets of subrings from being looped on the primary ring, first enable the primary ring on its master node. Then enable the subrings on their respective master nodes.

Example: Configuring dual-homed intersecting rings

Network configuration

As shown in Figure 5, a ring-shaped campus network is connected to a ring-shaped distribution layer network through an access layer device. Configure RRPP to implement the following requirements in the network:

· Eliminate loops and implement link recovery in the Layer 2 network.

· Implement link load balancing by forwarding voice traffic in VLAN 100 through VLAN 150 and video traffic in VLAN 151 through VLAN 200.

· Improve RRPP topology convergence speed by setting the physical state change suppression interval to 0 seconds for all Ethernet interfaces on the RRPP ring.

· Reduce the number of Edge-Hello packets.

Figure 5 Network diagram

Analysis

For voice and video traffic to be forwarded in different topologies, create four RRPP domains.

· In RRPP domain 1 and domain 4, specify VLAN 100 through VLAN 150 as protected VLANs, and configure the node roles as follows:

¡ Specify Device A as the master node of primary ring 1.

Restrictions and guidelines

When you configure dual-homed intersecting rings, follow these restrictions and guidelines:

· To avoid temporary loops when the primary ring fails, make sure the difference between the Fail timer values on the master node of the subring and primary ring is greater than twice the Hello timer value on the master node of the subring.

· When you configure an edge node or assistant edge node, you must configure the primary ring before configuring the subrings.

· When you configure load balancing, you must configure different protected VLANs for different RRPP domains.

· Before you enable subrings on a device, you must enable the primary ring. Before you disable the primary ring on the device, you must disable all subrings.

· If a device carries multiple RRPP rings in an RRPP domain, it can only be an edge node or an assistant edge node on a subring.

· To prevent Hello packets of subrings from being looped on the primary ring, first enable the primary ring on its master node. Then enable the subrings on their respective master nodes.

· Make sure all subrings in an RRPP ring group have the same SRPTs. You can assign a subring to only one RRPP ring group. For the RRPP ring group to operate correctly, the RRPP ring groups configured on the edge node and the assistant edge node must contain the same subrings.

· Make sure the RRPP ring groups on the edge node and the assistant edge node have the same configurations and activation status.
