Identifying Address Links for MAC Addressing

Why it is Important	Identifying the address links is an important step in configuring MAC Address
	filtering.
	A Source Address link allows a device on the LAN to send frames. A Destination
	Address link allows a device on the LAN to receive frames.
	The Incoming Source Address link provides a path for a frame to go from the Token
	Ring to the bridge. The Outgoing Source Address link provides a path for a frame to
	go from the bridge to the WAN.
	The Incoming Destination Address link provides a path for a frame to go from the
	WAN to the bridge. The Outgoing Destination Address link provides a path for a
	frame to go from the bridge to the LAN.
Example of
	Figure 33 shows that link 5 serves as both the Outgoing Source Address link and the
Address Links	Incoming Destination Address link. In this example, Outgoing Source Address link 5
	allows the File Server with MAC Address 10:00:5A:00:00:40 (the source) to send
	frames to the WAN via link 5. Incoming Destination Address link 5 allows the File
	Server with MAC Address 10:00:5A:00:00:40 (the destination) to receive frames
	from the WAN via link 5.
