Fig 1-9 shows an example of how to connect switch ports, that are configured for
multiple VLANs, to other switches.
As shown in Fig 1-9, switch SW1 is configured with multiple VLANs: ports 7, 15,
and 16 are in VLAN V1; ports 2, 4, 10, and 14 are in VLAN V2; and ports 1, 11,
and 12 are in VLAN V1+V2.
Switch SW1 can connect to switch SW2 because all of the ports on switch SW2
are configured in a single VLAN (VLAN V1). The same is true for switch SW3
where all of the ports are configured in a single VLAN (VLAN V2). In both of
these cases, the connection port from switch SW1 matches the configuration of
the other switch.
The connection to switch SW4 is also valid because, in this case, there is no
longer a distinction between VLANs V1 and V2. VLAN V1+V2 is, in effect, a
single VLAN that contains both broadcast domains.
Although switch SW4 is shown with all ports configured in VLAN V1+V2, any
of the ports can be assigned to additional VLANs as long as they are all in the
same VLAN membership as the connecting port (port 1).
Note: When connecting switches that have ports configured for multiple
VLANs, the multiple VLANs do not get projected across the connection. The
connection is treated as a single VLAN at the other end.
