RRPP Typical Configuration Examples 1155
■ Device D is the transit node of primary ring 1, GigabitEthernet 1/0/1 is the
primary port and GigabitEthernet 1/0/2 is the secondary port;
■ The timers of both the primary ring and the sub ring adopt the default value.

Configuration considerations
First, determine the primary ring and sub ring in an RRPP domain, node mode of a
device on each RRPP ring, and then perform the following configuration 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 an RRPP ring and the ports accessing the
RRPP ring on the device.
■ Enable these two RRPP rings.
■ Enable RRPP
