SW4 should never be root bridge
i have 4 switches sw1-sw2-sw3-sw4 they are interconnected through trunk
links . doesn't matter how i have given a task in work book lab ,what
config i do on other switches that sw4 would never be elected as root bridge in
any case if any of this switch is running... that means u can do the
config on sw1,sw2,sw3.....
apart from priority is if anyone can suggest me let me know... root gurard i tried but its not working in case sw4 has lower priority confiured ...
