The definition of routing and L3 forwarding should be the same. The interface is just the outgoing interface in the forwarding table. The device alters the L2 header and sends the frame out of that interface (L3 forwarding requires L2 header rewrite to get the frame to the next-hop). | |

Do you not think the/a difference between routing and forwarding is the decision between possible paths (routing) vs the simple lookup and forwarding on one fixed path that's defined in the forwarding table (forwarding) - as suggested by the answer to this related question? Also, what does "interface" mean in this context? | |
