Broadcast from E will be seen by all forwarding ports
3.10.2 Workgroup of Type IP
The destination IP address within the broadcast packet is used to
determine the workgroup (see Example #2). This IP address is
matched against the IP network address and IP network mask
defined in the workgroup for the receiving port. If the destination
IP address does not match the IP workgroup defined the packet is
forwarded out all other ports. If the destination IP address is a
broadcast address, the source IP address is used to determine the
correct workgroup. If there is no destination IP address(i.e. RARP),
then the packet is forwarded out all of the IP workgroups for the
receiving port. If the packet is an IP multicast but not broadcast
(i.e. class D address) the workgroups are ignored and the normal
forwarding criteria is applied.
Example #2
Defined workgroups:
workgroup red 3-5 All
workgroup blue 5-6 IP 100.100.1.0
255.255.255.0
workgroup green 6-7 IP 100.100.2.0
255.255.255.0
