Let me rephrase what I said in my most recent post. Suppose ports 1-5 AND ports 6-10 are running the SAME non-IP protocol and they want to talk but are in different VLANs. The switch can not route between the 2 VLANs if it is not IP. Thus, you bridge them. What I said before about appletalk communicating with DECNET I don't think made any sense :)

Raghav,
The way I understand it is this -- VLANs in general, and thus inter-vlan routing on a switch were designed around the IP protocol. Fallback bridging basically allows you to bridge non-ip protocols between VLANs. Since it is not IP it cannot be routed normally like an IP packet between vlans, so it can be bridged. I hope that helps

Hi Experts,
I was reading Fallback Bridging but somehow could not understand it.
Can someone please explain in simple terms.
Appreciate all the help..
