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

Figure 1-1 A single-ring topology

l
Device A, Device B, Device C and Device D
constitute RRPP domain 1.
l
VLAN 4092 is the control VLAN of RRPP domain 1.
l
Device A, Device B, Device C and Device D
constitute primary ring 1.
l
Device A is the master node of primary ring 1,
GigabitEthernet 1/0/1 is the primary port and GigabitEthernet 1/0/2 is the
secondary port.
l
Device B, Device C and Device D are the transit
nodes of primary ring 1, and their GigabitEthernet 1/0/1 is the primary port
and GigabitEthernet 1/0/2 is the secondary port.
l
The timer of the primary ring adopts the default
value.

The following describes the configurations on
Device A (master node) and Device B (transit node) only. The configuration on
Device C and on Device D is the same as that on Device B.
l
You must configure the ports accessing an RRPP
ring as trunk ports, permitting the traffic of data VLANs to pass through. For
details, refer to Ethernet Interface Configuration Guide in this manual.
l
You must disable STP on ports accessing RRPP
rings.

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.

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.

Device B is both the transit node of primary
ring 1 in RRPP domain 1 and the transit node of primary ring 2 in RRPP domain
2. GigabitEthernet 1/0/2 is the multi-domain intersecting common port.

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.
l
You must configure the ports in all domains
accessing an RRPP ring as trunk ports, permitting the traffic of data VLANs to
pass through. For details, refer to Ethernet Interface Configuration Guide
in this manual.

Disable STP on ports accessing RRPP rings.

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.
