The bridge determines that Host B is also attached to interface 1
Finally, the bridge obtains all the MAC-interface mappings (assume that all hosts are in use), as shown
in
.

The final bridge table
Forwarding and filtering
The bridge makes data forwarding or filtering decisions based on the following scenarios:
•
When Host A sends an Ethernet frame to Host C, the bridge searches its bridge table and finds out
that Host C is attached to bridging interface 2, and forwards the Ethernet frame out of bridging
interface 2, as shown in
.
