Operation Manual – RRPP
H3C S5500-EI Series Ethernet Switches
Device E, Device F, Device C and Device B constitute primary ring 2;
On primary ring 1 in RRPP domain 1, Device A is the master node,
GigabitEthernet 1/0/1 is the primary port and GigabitEthernet 1/0/2 is the
secondary port;
On primary ring 2 in RRPP domain 2, Device E is the master node,
GigabitEthernet 1/0/1 is the primary port and GigabitEthernet 1/0/2 is the
secondary port;
Device B is a transit node on primary ring 1 in RRPP domain 1 and a transit node
on primary ring 2 in RRPP domain 2, GigabitEthernet 1/0/2 is a multi-domain
intersection common port;
Device C is a transit node on primary ring 1 in RRPP domain 1 and a transit node
on primary ring 2 in RRPP domain 2, and GigabitEthernet 1/0/2 is a multi-domain
intersection common port;
Device D is a transit node on primary ring 1 in RRPP domain 1, GigabitEthernet
1/0/1 is the primary port and GigabitEthernet 1/0/2 is the secondary port;
Device F is a transit node on primary ring 2 in RRPP domain 2, GigabitEthernet
1/0/1 is the primary port and GigabitEthernet 1/0/2 is the secondary port;
Use default values for timers on the primary ring in each domain.

II. Configuration considerations
First, determine the node roles on the primary ring and subring in each RRPP domain,
and then perform the following configuration domain by domain on each device:
Create RRPP domains;
Specify the control VLAN for each domain;
Specify the node role of each device on each RRPP ring and the ports that access
the device to the RRPP rings;
Enable the RRPP rings;
Enable RRPP after completing the configuration of both domains.
