1.1 RRPP Overview
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:
zExpedited topology convergence
zIndependent of the number of nodes on the Ethernet ring

I. RRPP domain
The interconnected devices with the same domain ID and control VLANs constitute an
RRPP domain. An RRPP domain contains multiple RRPP rings, in which one ring
serves as the primary ring and other rings serve as subrings. You can set a ring as
either the primary ring or a subring.
As shown in Figure 1-1, Domain 1 is an RRPP domain, including two RRPP rings: Ring
1 and Ring 2.All the nodes on the two RRPP rings belong to the RRPP domain.
II. RRPP ring
Aring-shaped Ethernet topology is called an RRPPring. An RRPP domain is built up on
an RRPP ring. An RRPPring falls into primary ring and subring. Both levels are set to 0
and 1 respectively when configuration.
As shown in Figure 1-1, Domain 1 contains two RRPP rings: Ring 1 and Ring 2. Ring 1
level is set to 0, meaning the primary ring; Ring 2 level is set to 1, meaning the subring.
For a ring, there are two cases:
zHealth state: All the physical links on the Ethernet ring are connected.
zDisconnect state: Some physical link on the Ethernet ring fails.
III. Control VLAN and data VLAN
zControl VLAN is a VLAN specially designed to transfer RRPP packets. The ports
accessing an RRPP ring on devices belong to the control VLAN of the ring and
only these ports can join this VLAN. IP address configuration is prohibited on the
ports of the control VLAN. You can 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 systemand
its VLAN ID is the control VLAN ID of the primary ring plus 1.
zData VLAN is a VLAN designed to transfer data packets, including the ports
accessing the Ethernet ring and other ports on devices.
IV. Node
Every device on an RRPP ring is referred to as a node. Node mode includes:
zMaster node: Each ring has a master node primarily used to make loop detection
and loop guard.
zTransit node: All the nodes excluding the master node on the primary ring; and all
the nodes on a subring except for the master node and the nodes where the
primary ring intersects with the subring.
zEdge node: A node residing on the primary ring and a subring at the same time.
The node is a special transit node that serves as a transit node on the primary ring
and an edge node on the subring.
zAssistant-edge node: A node residing on the primary ring and a subring at the
same time. The node is a special transit node that serves as a transit node on the

Operation Manual – RRPP
H3C S3610&S5510 Series Ethernet Switches Chapter 1 RRPP Configuration
1-3
primary ring and an assistant-edge node on the subring. This node is used in
conjunction with the edge node to detect the integrity of the primary ring and
perform loop guard.
As shown in Figure 1-1, Ring 1 is the primary ring and Ring 2 is a subring. Device Ais
the master node of Ring 1, Device B, Device C and Device D are the transit nodes of
Ring 1; Device E is the master node of Ring 2, DeviceB is the edge node of Ring 2, and
Device C is the assistant edge node of Ring 2.
V. Primary port and secondary port
Each master node or transit node has two ports accessing an RRPP ring, in which one
serves as the primary port and the other serves as the secondary port. You can
determine the role of a port.
1) In terms of functionality, the difference between the primary port and the
secondary port of a master node is:
zThe primary port and the secondary port are designed to play the role of sending
and receiving loop-detect packets respectively.
zWhen an RRPP ring is in health state, the secondary port of the master node will
logically deny data VLANs and permit only the packets of the control VLANs.
zWhen an RRPP ring is in disconnect state, the secondary port of the master node
will permit data VLANs, that is, forward packets of data VLANs.
2) In terms of functionality, there is no difference between the primary port and the
secondary port of the transit node. Both are designed for the transfer of protocol
packets and data packets over an RRPP ring.
As shown in Figure 1-1, Device Ais the master node of Ring 1. Port 1 and port 2 are the
primary port and the secondary port of the master node on Ring 1 respectively. Device
B, Device C and Device D are the transit nodes of Ring 1. Their port 1 and port 2 are the
primary port and the secondary port on Ring 1 respectively.
VI. Common port and edge port
Each edge node or assistant edge node have two ports accessing a subring, with one
being a common port and the other being an edge port. Common port is a port
accessing the primary ring and a subring simultaneously; and edge port is a port
accessing only a subring.
As shown in Figure 1-1, Device B and Device C lie on Ring 1 and Ring 1. Device B’s
port 2 and Device C’s port 1 access the primary ring and a subring at the same time, so
they are common ports. Device B’s port 3 and Device C’s port 3 access only a subring,
so they are edge ports.

Operation Manual – RRPP
H3C S3610&S5510 Series Ethernet Switches Chapter 1 RRPP Configuration
1-4
VII. Multi-domain intersection common port
Of the two ports on a node where rings of different domains intersect, the common port
is the one on the primary ring that belongs to different domains at the same time. This
port must not be on a subring. The role of the port is determined by user configuration.
VIII. Timers
The master node uses two timers to send and receive RRPP packets: the Hello timer
and the Fail timer.
zThe Hello timer is used for the primary port to send Health packets.
zThe Fail timer is used for the secondary port to receive Health packets from the
master node.
If the secondary port receives the Health packets before the Fail timer expires, the
overall ring is in health state. Otherwise, the ring transits into disconnect state until the
secondary port receives the Health packet again.
Note:
zIn an RRPP domain, a transit node learns the Hello timer value and the Fail timer
value on the master node through the received Health packets, guaranteeing the
consistency of two timer values across a ring.
zThe Fail timer value must be greater than or equal to 3 times of the Hello timer
value.
1.1.2 RRPP Packets
Table 1-1 shows the types of RRPP packets and their functions.
Table 1-1 RRPP packet types and their functions
Type Description
Health The master node initiates Health packets to detect the
integrity of a ring in a network.
Link-Down The transit node, the edge node or the assistant edge node
initiates Link-Down packets to notify the master node the
disappearance of a ring in case of a link failure.
Common-Flush-FDB
The master node initiates Common-Flush-FDB packets to
notify the transit nodes to update their own MAC entries and
ARP entries when an RRPP ring transits to disconnect
state.

Operation Manual – RRPP
H3C S3610&S5510 Series Ethernet Switches Chapter 1 RRPP Configuration
1-5
Type Description
Complete-Flush-FDB
The master node initiates Complete-Flush-FDB packets to
notify the transit nodes to update their own MAC entries and
ARP entries, and release from blocking ports temporarily
when an RRPP ring transits into health state.
Edge-Hello The edge node initiates Edge-Hello packets to examine the
links of the primary ring between the edge node and the
assistant edge node.
Major-Fault Assistant edge node initiates Major-Fault packets to notify the edge node of a failure when a link of primary ring
between edge node and assistant edge node is torn down.

There are two or more domains in a network, and there two different common nodes
between any two domains. Figure 1-6 defines three RRPP domains, each containing
one and only one RRPPprimary ring. In the case of multi-domain intersection, the rings
in different domains are independently configured. Each single domain can contain
multiple rings, among which there must be one and only one primary ring. The data
VLAN in one domain must be isolated from the data VLAN in another.
1.1.4 How RRPP Works
I. Polling mechanism
The primary port of the master node sends Health packets across the control VLAN
periodically.
zIf the ring works properly, the secondary port of the master node will receive
Health packets and the master node will maintain it in block state.
zIf the ring is torn down, the secondary port of the master node will not receive
Health packets after the timeout timer expires. The master node will release the
secondary port from blocking data VLAN while sending Common-Flush-FDB
packets to notify all transit nodes to update their own MAC entries and ARP
entries.
II. Link down alarm mechanism
The transit node, the edge node or the assistant edge node sends Link-Down packets
to the master node immediately when they find any port belonging to an RRPP domain
is down. Upon the receipt of a Link-Down packet, the master node releases the
secondary port from blocking data VLAN while sending Common-Flush-FDB packet to
notify all the transit nodes, the edge nodes and the assistant nodes to update their own
MAC entries and ARP entries.
III. Ring recovery
The master node may find the ring is restored after a period of time after the ports
belonging to the RRPPdomain on the transit node, the edge node or the assistant edge
node are up again. A temporary loop may arise in the data VLAN in this period. As a
result, broadcast storm occurs.
To prevent temporary loops, non-master nodes block them immediately (and permits
only the packets of the control VLAN) when they find their ports accessing the ring are
up again. The blocked ports are activated only when the nodes ensure that no loop will
be brought forth by these ports.
IV. Broadcast storm suppression mechanism in a multi-homed subring in
case of primary ring link failure
As shown in Figure 1-5, Ring 1 is the primary ring, and Ring 2 and Ring 3 are subrings.
When two links of the primary ring between the edge node and the assistant edgenode

Operation Manual – RRPP
H3C S3610&S5510 Series Ethernet Switches Chapter 1 RRPP Configuration
1-9
are down, the master nodes of Ring 2 and Ring 3 will open their respective secondary
ports, and thus a loop among B, C, E and F is generated. As a result, broadcast storm
occurs.
In this case, to prevent from generating this loop, the edge node will block the edge port
temporarily. The blocked edge port is activated only when the edge node ensures that
no loop will be brought forth when the edge port is activated.
1.1.5 Protocols and Standards
Related standard: RFC 3619.
1.2 RRPP Configuration Task List

Configuring Assistant Edge Node Optional

Operation Manual – RRPP
H3C S3610&S5510 Series Ethernet Switches Chapter 1 RRPP Configuration

Caution:
zIt is recommended to configure the primary ring first and then the subring when you
configure an RRPP domain. Moreover, a Ring ID cannot be applied to more than
one RRPP ring in one RRPP domain.
zIf a device lies on multiple RRPP rings in an RRPP domain, only one primary ring
exists. The device serves as either an edge node or an assistant edge node on the
subrings.
zThe total number of rings configured on a device in allRRPP domains should not be
greater than 16.
zModification 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.
zThe secondary port on the master node and a port on a subring node must not be
configured as a multi-domain intersection common port, and the two ports that
access the same node to the same RRPP ring must not be configured as
multi-domain intersection common ports at the same time.
zWhen configuring multi-domain intersecting rings, do not enable or disable the
RRPP ring on which the multi-domain intersection common port resides with RRPP
globally enabled.
zIn the case of multi-domain intersection, the rings in different domains are
independently configured. Each single domain can contain multiple rings, among
which there must be one and only one primary ring. The data VLAN in one domain
must be isolated from the data VLAN in another.
The ports accessing an RRPP ring must conform to the following conditions:
zTrunk port;
zLayer 2 Ethernet port or Layer 2 GE port;
zExcept for aggregation port, loopback port and mirroring destination port;
zPort with STP, QinQ, 802.1x, MAC address authentication, voice VLAN and IP
Source Guard disabled;
zDo not enable OAM remote loopback function on an RRPP port. Otherwise, this
may cause temporary broadcast storm;

Operation Manual – RRPP
H3C S3610&S5510 Series Ethernet Switches Chapter 1 RRPP Configuration
1-11
Note:
zIf you need to transparently transmit RRPP packets on a device without enabling
RRPP, you should ensure only the two ports accessing an RRPP ring permits 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.
zDo not set the default VLAN ID of a port accessing an RRPP ring to primary control
VLAN ID or secondary control VLAN ID (the latter is equal to the former plus 1),
avoiding the influence on the proper receiving/sending of RRPP packets.

1.8 RRPP Typical Configuration Examples
This section covers these topics:
zConfiguring Single Ring Topology
zConfiguring Intersecting Ring Topology
1.8.1 Configuring Single Ring Topology
I. Networking requirements
zDevice A, Device B, Device C and Device D constitute RRPP domain 1;
zSpecify the control VLAN of RRPP domain 1 as VLAN 4092;
zDevice A, Device B, Device C and Device D constitute primary ring 1;
zSpecify Device A as the master node of primary ring 1, Ethernet 1/0/1 as the
primary port and Ethernet 1/0/2 as the secondary port;
zSpecify Device B, Device C and Device D as the transit nodes of primary ring 1,
their Ethernet 1/0/1 as the primary port and Ethernet 1/0/2 as the secondary port;
zThe timers of the primary ring adopt the default value.

II. Configuration considerations
First, determine the node mode of a device in an RRPP ring, and then perform the
following configurations on a per-device basis:
zCreate an RRPP domain.
zSpecify the control VLAN for the RRPP domain.
zSpecify the node mode of a device on the primary ring and the ports accessing the
RRPP ring on the device.
zEnable the RRPP ring.
zEnable RRPP
III. Configuration procedure
1) Perform the following configuration on Device A:
<Device A> system-view
[Device A] rrpp domain 1
[Device A-rrpp-domain1] control-vlan 4092
[Device A-rrpp-domain1] ring 1 node-mode master primary-port ethernet 1/0/1
secondary-port ethernet 1/0/2 level 0
[Device A-rrpp-domain1] ring 1 enable
[Device A-rrpp-domain1] quit
[Device A] rrpp enable
2) Perform the following configuration on Device B:
<Device B> system-view
[Device B] rrpp domain 1
[Device B-rrpp-domain1] control-vlan 4092
[Device B-rrpp-domain1] ring 1 node-mode transit primary-port ethernet 1/0/1
secondary-port ethernet 1/0/2 level 0
