Section V: Spanning Tree Protocols 237
A MSTI can contain more than one VLAN. This is illustrated in Figure 25
where there are two AT-9400 Switches with four VLANs. There are two
MSTIs, each containing two VLANs. MSTI 1 contains the Sales and
Presales VLANs and MSTI 2 contains the Design and Engineering VLANs.
Figure 25. Multiple VLANs in a MSTI
In this example, because an MSTI contains more than one VLAN, the links
between the VLAN parts is made with tagged, not untagged, ports so that
they can carry traffic from more than one virtual LAN. Referring again to
Figure 25, the tagged link in MSTI 1 is carrying traffic for both the Presales
and Sales VLANs while the tagged link in MSTI 2 is carrying traffic for the
Design and Engineering VLANs.
