Describe the behavior of an Ethernet bridge, comparing it to a repeater.

What will be an ideal response?

A newly installed Ethernet bridge initially behaves exactly like a repeater, passing frames from one segment to another. Unlike a repeater, the bridge changes this behavior once it has learned the MAC addresses of each port. After that, it filters traffic, meaning it stops traffic belonging on one connected network from crossing to the other network, and forwards only traffic that it has learned belongs on the other network.
