result from link failures. For example, the following figure shows a network containing VLANs 1 and 2. They are connected using the 802.1Q-tagged link between Switch B and Switch C. By default, this link has a port cost of 100 and is automatically blocked because the other Switch-to-Switch connections have a port cost of 36 (18+18). This means that both VLANs are now subdivided—VLAN 1 on Switch units A and B cannot communicate with VLAN 1 on Switch C, and VLAN 2 on Switch units A and C cannot communicate with VLAN 2 on Switch B.

Switch A

100Base TX full-duplex Link carry VLAN1 only (path cost =18)

	VLAN1
	VLAN2
Switch B
	Block
VLAN1	802.1Q tagged,
VLAN2	10Base Tx
	half-duplex Link
	carry VLAN1, 2
	(path cost =100)

100Base TX full-duplex Link carry VLAN2 only (path cost =18)

Switch C

VLAN1

VLAN2

To avoid any VLAN subdivision, it is recommended that all inter-Switch connections are made members of all available 802.1Q VLANs to ensure connectivity at all times. For example, the connections between Switches A and B, and between Switches A and C should be 802.1Q tagged and carrying VLANs 1 and 2 to ensure connectivity.

For more information about VLAN Tagging, see the section Configuring Virtual LANs.
