produces the same bridge arrangement as shown in Figure 10.
Figure 11. Example of Bridges in an SVC Arrangement
In this arrangement, all LAN segments are one hop away from each other since they
are directly attached by a single pair of bridges. In Figure 11, Token Ring 1 is one
bridge away from Token Ring 2 and Token Ring 3 and the same applies for the other
rings.
are directly attached by a single pair of bridges. In Figure 11, Token Ring 1 is one
bridge away from Token Ring 2 and Token Ring 3 and the same applies for the other
rings.
From a bridged network point of view, Token Ring 1 is one bridge away from Token
Ring 3, but Node 1 is not directly connected to Node 3. Traffic between Token Ring
1 and Token Ring 3 does not have to pass through Token Ring 2. This is an important
advantage in configuring bridge networks with the PathBuilder S200 series switch
because you can form a minimal bridge network to accomplish the desired
interconnectivity.
