To quickly configure interfaces and MSTP on Switch 3, copy the following commands and paste them into the switch terminal window:. Switch 4. I'm not entirely sure that I'm understanding the issue with the All access switches will be directly connected to the VC - STP is only used on access-ports in order to prevent loops. To fix it, do this on Juniper box set protocols vstp vlans all. This functionality provided by MSTP enables you to better utilize network resources while remaining backward-compatible with older network devices. Switch 1. Rule 4: No Low Quality Posts.
