Layer 2 broadcast address

[tony.thacheth]

Hi..

As I understood ff.ff.ff.ff.ff.ff is a layer 2 broadcast address and 10.10.10.255/24 is Layer 3 broadcast address.

As per understanding this layer 2 address should convert to layer 2 mac address. So what will be the layer 2 address for 10.10.10.255/24

Advance thanks for your help

Your example: 10.10.10.255/24 is a "directed-broadcast". It is a "broadcast" intended for the 10.10.10.0/24 IP subnet. Once the packet reaches the 10.10.10.0/24 subnet, it is then sent on l2 broadcast ff:ff:ff... to all stations on that subnet.
