Forwarding And Filtering - HP MSR SERIES Configuration Manual

Figure 283 The bridge determines that Host B is also attached to interface 1
MAC address: 00e0.fcaa.aaaa
MAC address: 00e0.fccc.cccc
Finally, the bridge obtains all the MAC-interface mappings (assume that all hosts are in use), as shown
in Figure 284.

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
