Private VLANs and broadcast traffic separation

http://www.mdh.se/netcenter/ct3690/ht-2005/forelas/Private_vlans.pdf#search=%22private%20vlan%22

((A VLAN on a network is a broadcast domain, and all of the hosts on that VLAN can communicate with the other members of the same VLAN.

PVLANs allow traffic to be segmented at the data-link layer (layer 2) of the OSI model, limiting the size of the broadcast

domain)).

Was it meant by word "traffic" in this phrase : "PVLANs allow traffic to be segmented ", broadcast traffic ? (i.e. Does that mean each PVLAN have its own broadcast domain ?)

Re: Private VLANs and broadcast traffic separation

Hi,

VLANs create broadcast domains at layer2,

Usually broadcast domains are created by layer3 device but by using vlan we can create them at layer 2 device which are logical broadcast domains

Yes each VLAN Creates its own broadcast domain and to have communication between two vlans we need a layer3 device for this.

Thanks,
