Broadcast Domains Although switches filter most frames based on MAC addresses, they do not filter broadcast frames. For other switches on the LAN to get broadcasted frames, broadcast frames must be forwarded by switches. A collection of interconnected switches forms a single broadcast domain. Only a Layer 3 entity, such as a router, or a virtual LAN (VLAN), can stop a Layer 3 broadcast domain. Routers and VLANs are used to segment both collision and broadcast domains. The use of VLANs to segment broadcast domains will be discussed in the next chapter.
