3.3 Configuring RRPP Functions

Through RRPP, devices on an Ethernet ring are configured to be the nodes with different roles
on RRPP rings. The nodes on an RRPP ring detect the ring status and transmit topology changes
by sending and receiving RRPP protocol packets. The master node on an RRPP ring blocks or
opens secondary ports according to the ring status. In this manner, if a fault occurs on a node or
a link on the RRPP ring, traffic can be fast switched to the backup link and data loops can be
prevented.

3.3.1 Establishing the Configuration Task

If you have already enabled RRPP on a port, you cannot enable STP on it. That is, the two
protocols cannot coexist on a port.
Applicable Environment
RRPP is used for the networking of the single-ring or multiple crossed rings. When configuring
RRPP, you must configure all nodes on the RRPP ring.
Pre-Configuration Tasks
Before configuring RRPP functions, complete the following tasks:

3.3.2 Creating Instances

Issue 01 (2011-10-26)
NOTE
The RRPP or the STP can not coexist on a port.
RRPP contains no auto election mechanism. Therefore, to ensure the detection and protection of the ring
network through RRPP, you must correctly configure each node on the ring.
