Re: L 4 bridging

Hi Friend,

Inter-VLAN bridging is the concept of simultaneously bridging multiple VLANs together. Inter-VLAN bridging is occasionally needed in order to bridge non-routable protocols or unsupported routed protocols between multiple VLANs.

In Cisco Terminology it is also known as FALL BACK Bridging

Hi Friend,

I think L4 switching or bridging is just a marketting terminology but it is just switching and bridging using layer 4 information of any frame.
