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
■
Configuration procedure
