Changing the priority of a non-zero region MSTP instance results in BPDUs advertising a change to the CIST Bridge Priority, but not for the expected MSTID instance.
Changing the MSTID priority for forcing the BIG-IP system to become the root bridge, does not work as expected. Note: F5 Networks recommends against having the BIG-IP system become the root bridge.
Issue a STP MSTID priority modify request.
After modifying the MSTID priority, also restart the STP daemon (stpd) to have the BPDUs advertising the expected CIST/MSTID priorities.
