RPVS Spanning Tree Issue in simulator software (GNS3 and EVE-NG)

[Eddyjr81]

Hello,

I'm having trouble getting Spanning Tree to work properly in OS-CX (tested in both EVE-NG and GNS3, always with the same result).

I’ve set up a basic configuration with Spanning Tree enabled on two switches. When one node pings the other, some pings time out. Does anyone know if I'm doing something wrong, or if this is a limitation of the emulation environment? I’ve also tried different firmware versions for the switches, but the result remains the same. I’m attaching a diagram and switch configuration.

Thank you for any help!
