RSTP question with 3 paths

RouterOS Forwarding Protocols
1

I have a test setup using RSTP that is as follows:

SwitchA connects to Switches B, C, D.

B<>C

C<>D

All traffic is flowing from A to B and A to D, but C only gets traffic via B or D. Even though C is only one hop from A.

Am I approaching this wrong?

I basically just bridged the interfaces and enabled RSTP. All links are the same speed etc. I’d like traffic to be able to traverse from A to C directly, A to B and A to D directly as well. If any of the A to ? links should fail, the other links will allow the traffic to go around the outage.

Thanks!

This is exactly the behavior of spanning tree. On a redundant network it will disable paths in order to avoid loops. So you’ll see that sometimes traffic flows in a way that’s counter intuitive.

what you’re trying to achieve involves making A the root bridge. Lower the bridge priority on A and it should converge the way you want.

Awesome, thanks! That did the trick! I have always used OSPF so this is a new attempt at dealing with failover and it is working great now.
