Four-Alteon Topology with Multiple Spanning Trees
If multiple spanning trees are implemented and each VLAN is on a different spanning tree,
elimination of logical loops will not isolate any VLAN.
Figure 9 - Four-Alteon Topology with a Multiple Spanning Tree, page 104
shows the same four-
Alteon topology as in Figure 8 - Four-Alteon Topology with a Single Spanning Tree, page 104
, but
with multiple spanning trees enabled. The VLANs are identified on each of the three shaded areas
connecting the Alteons. The port numbers are shown next to each Alteon. The STG number for each
VLAN is shown at each Alteon.
