Because DLSw+ does not do local translation between different LAN types, Router B must be
configured for SR/TLB by issuing the source-bridge transparent command. Also, note that the bridge
groups are configured on the ethernet interfaces.
DLSw+ Translation Between FDDI and Token Ring Configuration Example
DLSw+ also supports FDDI media. The configuration is similar to other DLSw+ configurations except
for configuring for a specific media type. The following example shows FDDI media (see Figure 136).
Figure 136 DLSw+ Translation Between FDDI and Token Ring
In the following configuration, an FDDI ring on Router A is connected to a Token Ring on Router B
across a DLSw+ link.
