how a BPDU passes through a blocked port of switch where we all know that blocked port can't able to pass any frames.

Any answer please? icon_cool.gif

    Blocked ports do not transmit BPDUs, but they can receive BPDUs.

    Switches do not break up Broadcast domains, only collision domains, A switch (well most) work at layer 2 of the OSI model. A broadcast is sent out to all addresses on a subnet
    so a subnet of 255.255.255.0 192.192.168.0 the broadcast address is 192.192.168.255 the addresses everything on the network

    only Routers (layer 3) devide broadcasts as they work across subnets, also a switch can devide broadcasts by using VLAN's so 2 Vlans create 2 broadcast domains.
    Looking for CCIE lab study partnerts, in the UK or Online.
