Is the router a collision domain?

Its a multiple broadcast domain, but is the router also a collision domain?

Thanks,

No, the router itself doesn't have a collision domain. A router only creates multiple broadcast domains.

no!all!

As Binary Freak said routers break up broadcast domains and swicthes break up collision domains. Remember, by default, routers don't forward broadcasts.

Hi no!all!

I have noticed you are from Baltimore, what area?

I'm pretty sure each port on a router is also its own collision domain. Typically though in tests, routers are used to separate broadcast domains and switches create more collision domains.

Routers separate both Collision and Broadcast Domains by default, Switches separate collision domains by default, with vlans also separating broadcasts.
