Dual homed rings configuration example
Networking requirements
As shown in
Figure
22 ,
• Device A through Device H form RRPP domain 1. Specify the primary control VLAN of RRPP domain
1 as VLAN 4092, and specify that RRPP domain 1 protects VLANs 1 through 30.
• Device A through Device D form primary ring 1. Device A, Device B, and Device E form subring 2.
Device A, Device B, and Device F form subring 3. Device C, Device D, and Device G form subring
4. Device C, Device D, and Device H form subring 5.
• 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 E as the master node of subring
2, GigabitEthernet 1/0/1 as the primary port and GigabitEthernet 1/0/2 as the secondary port.
Specify Device F as the master node of subring 3, GigabitEthernet 1/0/1 as the primary port and
GigabitEthernet 1/0/2 as the secondary port. Specify Device G as the master node of subring 4,
GigabitEthernet 1/0/1 as the primary port and GigabitEthernet 1/0/2 as the secondary port.
Specify Device H as the master node of subring 5, GigabitEthernet 1/0/1 as the primary port and
GigabitEthernet 1/0/2 as the secondary port.
• Specify Device A as the edge node of the connected subrings, its GigabitEthernet 1/0/3 and
GigabitEthernet 1/0/4 as the edge ports. Specify Device D as the transit node of the primary ring
and edge node of the connected subrings, its GigabitEthernet 1/0/3 and GigabitEthernet 1/0/4
as the edge ports. Specify Device B and Device C as the transit node of the primary ring and
assistant-edge nodes of the connected subrings, their GigabitEthernet 1/0/3 and GigabitEthernet
1/0/4 as the edge ports.
NOTE:
Configure the primary and secondary ports on the master nodes properly to ensure that other protocols
still work normally when data VLANs are denied by the secondary ports.
