HP Multi-Domain Single Ring (RRPP) with IRF Stacking

Operational The goal in this case is to have 2 ranges of vlan’s that will go over a different side of the ring. If 1 side of the ring fails the vlan’s will still be active but over the same side of the ring. With the stacking we can use both switches as active since the ring start on the master switch and end on the slave switch. Like this we can get maximum use of our ring topology. You can use your own range of vlan’s and ports off course depending on the switches you have and use case.

At this point, you can cross-connect the switches. You have to connect Ten-GigabitEthernet 1/0/1 to Ten-GigabitEthernet 2/0/2, and Ten-GigabitEthernet 1/0/2 to Ten-GigabitEthernet 2/0/1. This is important! The second switch will join the stack, and it will reboot. If the second switch has a different firmware version, the firmware is updated after the join and the switch will reboot again. After the completion of the reboot, you can check the IRF configuration with the command

Multi-Domain Single Ring
Network diagram for a multi-domain single-ring network   A multi-domain single-ring network has only one ring, but multiple VLANs for the purpose of load sharing. Multiple RRPP domains are configured in the network, each having its own protected VLANs. In addition, an RRPP ring has different master nodes in different RRPP domains or has the same master node but different primary/secondary ports in different RRPP domains. Therefore, the protected VLANs of different RRPP domains have different logical topologies. We use different Master nodes Domain 1 (DeviceA) Domain 2 (DeviceD)
Configuration Domain 1
Configuration on Device A. Create VLANs 1 through 2050, map these VLANs to MSTI 1, and activate the MST region configuration.

Disable physical state change suppression and STP on GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2, configure the two ports as trunk ports, and assign them to VLANs 1 through 2050, and configure them to trust the 802.1p precedence of the received packets.

Configure Device A as the master node of primary ring 1, with GigabitEthernet 1/0/21 as the primary port and GigabitEthernet 2/0/21 as the secondary port, and enable ring 1.
