I am designing a network for industrial purpose, and I have some doubts designing the Rapid/Multiple Spanning Tree Redundancy.
My two core switches are Cisco Catalyst 3750G but all the other devices in the network are Non-Cisco. If you take a look in the drawing I attach you will see the topology. Each ring is planned to have around 30-35 switches
- The core switch 1 is configured as root bridge (prio 4096) and the switch 2 as backup root (prio 8192). All the other switches have prio 32768.
- Each of the links shown in the diagram (red,blue,black) are trunk ports. Each ring has 4 different VLANs and one VLAN (VID 100) shared by both rings.
- The Non-Cisco devices can only work with RSTP. The colors are just to distinguish between physical rings.
- Core 1 and Core 2 are in different buildings. That's the reason for the cross-connections.
My question is, how do I have to configure both Cisco to make them able to see Ring A as a single RSTP domain and Ring B as another single RSTP domain? I am pretty new with this issues and I am getting some problems understanding the operation of both protocols together.......
