Rapid Ring Protection Protocol (RRPP) is an Ethernet ring-specific link layer protocol. It can not only prevent data loop from causing broadcast storm efficiently when the Ethernet ring is complete, but also restore communication channels among nodes on the Ethernet ring rapidly when a link is torn down. Compared with Spanning Tree Protocol (STP), RRPP features:

l Expedited topology convergence

l Independent of the number of nodes on the Ethernet ring

Configuration Guidelines

l RRPP does not have an auto election mechanism, so you must configure each node in the ring network properly for RRPP to monitor and protect the ring network.

l Before configuring RRPP, you need to construct a ring-shaped Ethernet topology physically.

l Control VLAN configuration is required for configuring an RRPP ring.

l The control VLAN configured for an RRPP domain must be a new one.

l You can only configure a control VLAN for the primary ring (namely the primary control VLAN). However, the control VLAN of a subring (namely the secondary control VLAN) is assigned automatically by the system and its VLAN ID is the control VLAN of the primary ring plus 1. Therefore, you must use two new continuous VLANs when configuring a control VLAN. Otherwise, the configuration fails.

l Each RRPP domain is bound to a control VLAN only. You will remove a control VLAN when removing an RRPP domain. However, you cannot use the undo vlan all command to remove a control VLAN.

l You cannot specify a control VLAN as a remote mirroring VLAN or an isolate-user-VLAN.

l Do not enable QinQ or VLAN mapping on the control VLAN. Otherwise, RRPPDUs cannot be forwarded properly.

l Do not configure the default VLAN of a port accessing an RRPP ring as the primary control VLAN or the secondary control VLAN, ensuring proper receiving/sending of RRPP packets.

l Modification of node mode, port role and ring level of an RRPP ring is prohibited after configuration. If needed, you must first delete the existing configuration.

l To use the undo rrpp domain command to remove an RRPP domain, you must ensure the RRPP domain has no RRPP ring.

l You must configure the ports accessing an RRPP ring as trunk ports, permitting the traffic of data VLANs to pass through.

l Ports accessing an RRPP ring must not be aggregate ports or service loop ports.

l You must not enable STP, 802.1x, MAC address authentication, voice VLAN or smart link on ports accessing an RRPP ring.

l Do not enable OAM remote loopback function on an RRPP port. Otherwise, this may cause temporary broadcast storm.

l Enable link status rapid report function on a port accessing an RRPP ring (the link-delay of the port is set to 0) to accelerate topology convergence.

l If you need to transparently transmit RRPP packets on a device without enabling RRPP, you must ensure that only the two ports accessing an RRPP ring permit the packets of the control VLAN. Otherwise, the packets from other VLANs may go into the control VLAN in transparent transmission mode and strike the RRPP ring.

Configuration Guidelines

In addition to the precautions in Configuration Guidelines in Configuring a Single-Ring Topology, make sure that:

l You must first configure the primary ring and then the subring when configuring an RRPP domain. In addition, different RRPP rings in the same RRPP domain cannot share the same ring ID.

l If a device is on multiple RRPP rings in the same RRPP domain, only one primary ring exists. Moreover, the node role of the device on other subrings can be either edge node or assistant edge node only.

l You do not need to configure the level values when using the ring command to configure an edge node or an assistant edge node.

l The total number of rings configured on a device in all RRPP domains cannot be greater than 16.

l Do not configure the default VLAN of a port accessing an RRPP ring as the primary control VLAN or the secondary control VLAN (the secondary control VLAN is the control VLAN plus 1), ensuring proper receiving/sending of RRPP packets.

l You must first configure the primary ring and then the subring when configuring an edge node or an assistant edge node. Moreover, you must remove all subring configurations before deleting the primary ring configuration of an edge node. However, the RRPP ring enabled cannot be deleted.

Configuration Guidelines

In addition to the precautions in Configuration Guidelines of Configuring a Single-Domain Intersecting-Ring Topology, make sure that:

l Multi-domain intersecting rings must have their primary rings intersected. In another word, you cannot configure a port on a subring node as a multi-domain intersecting common port.

l You cannot configure the secondary port on the master node as the common port of the multi-domain intersecting rings when it is blocked.

l You cannot configure a node’s two ports accessing the same RRPP ring as the multi-domain intersecting common ports simultaneously.

l With RRPP enabled globally, you cannot enable or disable the RRPP rings on which the multi-domain intersecting common port resides when configuring multi-domain intersecting rings.

l The rings within different domains are independent when you configure multi-domain intersecting rings. Data VLANs in different domains must be isolated from each other.

2 RRPP Configuration Guide (Protected VLANs Supported)

To be compatible with old-version RRPP, which does not support protected VLAN configuration, an RRPP domain protects all VLANs on a device started with an old-version configuration file.

Configuration Guidelines

l RRPP does not have an auto election mechanism, so you must configure each node in the ring network properly for RRPP to monitor and protect the ring network.

l Before configuring RRPP, you need to construct a ring-shaped Ethernet topology physically.

l Before configuring rings for an RRPP domain, you must configure protected VLANs and protected VLANs for the domain first.

l The control VLAN configured for an RRPP domain must be a new one.

l Each RRPP domain is bound to a control VLAN only. You will remove a control VLAN when removing an RRPP domain. However, you cannot use the undo vlan all command to remove a control VLAN.

l You cannot specify a control VLAN as a remote mirroring VLAN or an isolate-user-VLAN.

l Do not enable QinQ or VLAN mapping on the control VLAN. Otherwise, RRPPDUs cannot be forwarded properly.

l Do not configure the default VLAN of a port accessing an RRPP ring as the primary control VLAN or the secondary control VLAN, ensuring proper receiving/sending of RRPP packets.

l Protected VLAN configuration is required for configuring an RRPP ring. After specifying rings for an RRPP domain, you can delete or modify the protected VLANs configured for the RRPP domain, however, you cannot delete all the protected VLANs configured for the domain.

l The protected-vlan command configures protected VLANs for an RRPP domain by referencing MSTIs to which the protected VLANs are mapped. When the VLAN-to-MSTI mappings change, the protected VLANs of an RRPP domain also changes according to the MSTIs configured for the domain.

l All the VLANs permitted to pass through RRPP ports must be configured as protected VLANs of the RRPP domain.

l To activate the RRPP domain, RRPP protocol and the RRPP ring must be enabled simultaneously.

l Modification of node mode, port role and ring level of an RRPP ring is prohibited after configuration. If needed, you must first delete the existing configuration.

l To use the undo rrpp domain command to remove an RRPP domain, you must ensure the RRPP domain has no RRPP ring.

l You must configure the ports accessing an RRPP ring as trunk ports, permitting the traffic of data VLANs to pass through.

l Ports accessing an RRPP ring must not be member ports of any aggregation group, service loopback group, or smart link group.

l You must not enable STP, 802.1x, MAC address authentication, voice VLAN or smart link on ports accessing an RRPP ring.

l Do not enable OAM remote loopback function on an RRPP port. Otherwise, this may cause temporary broadcast storm.

l Enable link status rapid report function on a port accessing an RRPP ring (the link-delay of the port is set to 0) to accelerate topology convergence.

Configuration Guidelines

In addition to the precautions in Configuration Guidelines in Configuring a Single-Ring Topology, make sure that:

l You must first configure the primary ring and then the subring when configuring an RRPP domain. In addition, different RRPP rings in the same RRPP domain cannot share the same ring ID.

l You do not need to configure the level values when using the ring command to configure an edge node or an assistant edge node.

l To enable subrings, you must first enable the primary ring before enabling subrings. You must first disable all the subrings in the RRPP domain and then disable the primary ring.

l The total number of rings configured on a device in all RRPP domains cannot be greater than 16.

Configuring Intersecting-Ring Load Balancing

In a ring network, maybe traffic of multiple VLANs is transmitted at the same time. RRPP can implement load balancing for the traffic by transmitting traffic of different VLANs along different paths.

By configuring an individual RRPP domain for transmitting the traffic of the specified VLANs (refereed to as protected VLANs) in a ring network, traffic of different VLANs can be transmitted according to different topologies in the ring network. In this way, load balancing is achieved.

Network Diagram

Networking and Configuration Requirements

l Device A, Device B, Device C, Device D, and Device F constitute RRPP domain 1, and VLAN 100 is the control VLAN of the RRPP domain. Device A is the master node of the primary ring Ring 1; Device D is the transit node of the primary ring Ring 1; Device F is the master node of the subring Ring 3; Device C is the edge node of the subring Ring 3; Device B is the assistant-edge node of the subring Ring 3.

l Device A, Device B, Device C, Device D, and Device E constitute RRPP domain 2, and VLAN 105 is the control VLAN of the RRPP domain. Device A is the master node of the primary ring Ring 1; Device D is the transit node of the primary ring Ring 1; Device E is the master node of the subring Ring 2; Device C is the edge node of the subring Ring 2; Device B is the assistant-edge node of the subring Ring 2.

l Specify VLAN 10 as the protected VLAN of domain 1, and VLAN 20 as the protected VLAN of domain 2. Thus, you can achieve VLAN-based load balancing on the primary ring.

l As the edge node and assistant-edge node of subring Ring 2 is the same as those of subring Ring 3, and the two subrings have the same link in the primary ring, you can add subrings Ring 2 and Ring 3 to the ring group to reduce Edge-Hello traffic.

Configuration Guidelines

In addition to the precautions in Configuration Guidelines of Configuring a Single-Ring Topology and Configuration Guidelines of Configuring a Intersecting-Ring Topology, make sure that:

l To reduce Edge-Hello traffic, you can adopt the ring group mechanism, that is, assign subrings with the same edge node/assistant-edge node to a ring group. RRPP configured with ring groups cannot interoperate with RRPP that does not support ring group configuration.

l You need to configure ring groups on both the edge node and the assistant-edge node at the same time. The two ring groups must be configured with the same subrings. Otherwise, the ring groups cannot operate properly.

l A subring can be assigned to only one ring group.

l A device must be of the same type, an edge node or an assistant-edge node, in the subrings in a ring group.

l To assign an activated ring to a ring group, first assign the ring to the assistant-edge node ring group and then to the edge node ring group.

l To remove an activated ring from a ring group, first remove the ring from the edge node ring group and then from the assistant-edge node ring group.

l The subrings in a ring group must have the same link in the primary ring. Otherwise, the ring group cannot function properly.

l An edge node ring group and its corresponding assistant-edge node ring group must be the same in configurations and activation status.
