RRPP Typical Configuration Examples 1153
Configuring Single Ring
Topology
Networking requirements
■ Device A, Device B, Device C and Device D constitute RRPP domain 1;
■ Specify the control VLAN of RRPP domain 1 as VLAN 4092;
■ Device A, Device B, Device C and Device D constitute primary ring 1;
■ Specify Device A as the master node of primary ring 1, GigabitEthernet 1/0/1 as
the primary port and GigabitEthernet 1/0/2 as the secondary port;
■ Specify Device B, Device C and Device D as the transit nodes of primary ring 1,
their GigabitEthernet 1/0/1 as the primary port and GigabitEthernet 1/0/2 as
the secondary port;
■ The timers of the primary ring adopt the default value.

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:
■ Create an RRPP domain.
■ Specify the control VLAN for the RRPP domain.
■ Specify the node mode of a device on the primary ring and the ports accessing
the RRPP ring on the device.
■ Enable the RRPP ring.
■ Enable RRPP
