866Appendix E: REPORT EXAMPLES
Network Configuration 1
Bridging between VLANs can cause the same MAC address to appear on different ports. See example below. If the host on VLAN1 sends a packet to the server on VLAN2, the packet first goes to the switch and is learned on port X in VLAN1. The packet then goes to the brouter. If the protocol being used is one that is being bridged as opposed to routed, then the brouter will bridge the packet back to the switch. Thus the host MAC address is also learned on port Y on VLAN2.
