Hi,

Fallback bridging works only for non-routed protocols, not IP.

<doccd>
this chapter describes how to configure fallback bridging (VLAN
bridging) on your Catalyst 3550 switch. With fallback bridging, you
can forward non-IP packets that the switch does not route between VLAN
bridge domains and routed ports.
