Routing Loops

Hi,

I made the following poc setup

Now the problem is when attaching the star. The network is looping hard.

On all the interfaces loop protections is enabled. RSTP is configured.

There’s something i did wrong but i can’t pin point the problem.

Hey. There is no any picture attached. And RSTP is layer 2 protocol, its about switching, not routing.

See Attached picture of the setup. As you can see the SW0-4 are layer 2

Found the loop.
Loop what caused the problem was between the RT01 and RT02

Now it’s time to make a little interface script.
