Mstp instances with 2 Vlan and 4 switchs

Hi,
Can you confirm config parameters in my attachement.
Thanks.

That would be fine for the priorities. You'd also need to set the config-revision and assign VLANs to those instances.

If switch 1 and switch 2 are going to be redundant routers (XRRP or VRRP), then I probably wouldn't bother setting priority values for switches 3 & 4. Leaving them at the default of 8 should be okay.

I strongly recommend you update to K.12.51 and I.10.43 which both support the auto-edge-port feature. This will greatly reduce the amount of topology changes your network is currently seeing which will decrease unnecessary flooding.
