About Collision or Broadcast domain

When a Router have VLan or Bridge on the interface. In this time how can i calculate Broadcast and Collision domain


  • Each router interface is its own broadcast and collision cc domain. Vlan also separates domains

  • Every switchport is its own collision domain. Every VLAN and every router interface defines a broadcast domain

  • Routers and vlan separates brodacast domains.Switches and bridges separate collision domains
