L3 to L2

Hi Cory,
What exactly are you trying to achieve?  If you can give us an idea of what packets from which IP addresses via which  "layer 3 IP address" on the router to which "layer 2 interface within the router" you are trying to dircect and for what purpose, you'd have a better chance of getting a reply. And remember... a picture is worth a thousand words.

I agree with RedNectar

you need to describe your problem and your setup with more details to get proper solution also if you can attach diagrams that is will be better to solve your issue quickly 
 

L3 "switches" are effectively L2 switches with a bolted on (internal) router. If the router allows / routes a packet, the the switch engine will use that for subsequent packages making the switching process a bit more efficent.

The ports on a L3 switch are common ordinary Ethernet ports. (Ethernet operates on L1  (copper, fibre, ..) with L2 for Addressing & packet formats)..

So what exactly is your question about... L1 (cabling etc...), probably not,   L2 (MAC addressing, Ethernet packets and handling), L3 ( aka IP routing).

No, you cannot pass traffic from L3 (routing) to L2 port (switching). They only communicate in the same level.

are you asking about Router-in-a-stick or L3 switch?

@DP320 you mean L3 ethernet (802.3) is different from L2 ethernet(802.3)???? Are you really sure?
The switches are different... the ports are not. L3 is "inside" the box... and if you want L3 failover functionality THEN L2 boxes cannot deliver on that as they are missing L3 functionality.

Let's the author explain, I'm not quite sure we understood this question properly!

Appreciate the feedback. I have a failover network that is using L3 routed interfaces to communicate internal VLANs throughout my infrastructure. I do have a L3 switch connected to my router using my switchport module to connect the 2 devices, but I have servers I need to access on the L3 Switch, no extra 1G routed port on my router but I do have a 10G port available.
