You can configure the ATM logical interface as either an Ethernet ATM
bridge tunnel or an FDDI ATM bridge tunnel. To minimize the number of points at which
Ethernet-to-FDDI translation is required, you should configure the bridge tunnel according
to the following guidelines:
If. . .
Then. . .
Source and
destination devices on either side of an ATM cloud are both on Ethernet LANs
The tunnel
should be an Ethernet ATM bridge tunnel.
Either the
source or destination device is on an FDDI ring, and the other device is on an Ethernet
LAN
The tunnel
should be an FDDI ATM bridge tunnel.

destination devices on either side of an ATM cloud are both on an FDDI ring
