Basic RRPP concepts

Figure 12 shows a typical RRPP network with two Ethernet rings and multiple nodes. RRPP detects ring
status and sends topology change information by exchanging Rapid Ring Protection Protocol Data Units
(RRPPDUs) among the nodes.

RRPP domain
An RRPP domain is uniquely identified by a domain ID. The interconnected devices with the same domain
ID and control VLANs constitute an RRPP domain. An RRPP domain contains the following elements:
Primary ring and subring.
•
Control VLAN.
•
Master node, transit node, edge node, and assistant edge node.
•
Primary port, secondary port, common port, and edge port.
•
As shown in
the nodes on the two RRPP rings belong to the RRPP domain.
RRPP ring
A ring-shaped Ethernet topology is called an RRPP ring. RRPP rings include primary rings and subrings.
You can configure a ring as either the primary ring or a subring by specifying its ring level. The primary
ring is of level 0, and a subring is of level 1. An RRPP domain contains one or multiple RRPP rings, one
serving as the primary ring and the others serving as subrings. A ring can be in one of the following
states:
Health state—All physical links on the Ethernet ring are connected.
•
Disconnect state—Some physical links on the Ethernet ring are not connected.
•
As shown in
1 and 1 for Ring 2. Ring 1 is configured as the primary ring, and Ring 2 is configured as a subring.
Control VLAN and data VLAN
